Cairo Tiling‎ > ‎

Miscellaneous

A miscellaneous, largely ‘for fun’ collection of various non in situ Cairo tiling aspects, in which the Cairo tiling is to be seen in a variety of objects and applications. The format is a picture and discussion. On occasions, I am unable to show pictures as the image holder did not respond to request for permissions, and where this arises I thus instead give a link. I began by placing sightings individually, broadly as found, rather than as a type, such as all instances of tables and panels etc. However, as of the 2019 return, I now place as to type, which at least gives a modicum of order. Note that the compilation is of an ad hoc nature, of instances as found upon my researches, and therefore the collection, being in a permanent state of flux (and so on occasion inconsistent, especially as regards numbering), is not particularly ordered in any way. Instances of pavings, wall tiles, floors and architecture, of which there are many, that once were included have been better judged placed as separate, dedicated pages (as of April 2019). Does anyone know of other instances? Do let me know for inclusion. The instances include:

1. Bisymmetric Hendecahedron (1), by Jak Drinnan


Another curiosity of the Cairo tiling is that it can be seen in an instance of polyhedra, specifically of the space-filling Bisymmetric Hendecahedron. Such a polyhedron is a relatively recent discovery, as reported in a 1996 paper by Guy Inchbald. For further details see:

http://www.steelpillow.com/polyhedra/five_sf/five.htm

Although the Cairo tiling as an entity was not directly noticed in Inchbald’s paper, an architect, Jak Drinnan, happened to notice this, and being familiar with the Cairo tiling made the association.

Although I am interested in polyhedra, this is very much secondary to my interest in tessellation. Indeed, I lack the mathematics here for a true mathematical treatment. Would any reader more familiar with this have anything to say?

For more on Jak Drinnan and the bisymmetric hendecahedron per se, see:

2. Shower Base (1), by John Mansfield

An instance of a modern-day self-design is of bathroom floor at the home of John Mansfield, in North Potomac, Maryland, USA (about 25 miles north by north-west from the centre of Washington, D.C). This was built during the summer of 2014. The material is porcelain. The Cairo tiling was specially chosen for the project. John told me;
I wanted to do something mathematically interesting. I considered Penrose tilings, but in the small space of a bathroom it would be hard to appreciate that that pattern, though non-periodic, is not merely random. Plus I didn't like the look of that so much. Looking about tesselations, I came upon periodic arrangements of pentagons. I liked the interlacing of the two systems of hexagons. Building the floor with equilateral pentagons would allow an interesting geometric construction.

6. Penta-graphene (1) Discovery

A recent development (February 2015) concerning the Cairo tiling is in the form of a scientific discovery, of ‘Penta-graphene’. Researchers at Virginia Commonwealth University (VCU) and universities in China and Japan have discovered a new structural variant of carbon called ‘Penta-graphene’ – a very thin sheet of pure carbon that has a unique structure inspired by the Cairo tiling. The newly discovered material is a single layer of carbon pentagons that resembles the Cairo tiling, and that appears to be dynamically, thermally and mechanically stable and can withstand temperatures up to 1,000 K (730 °C; 1,340 °F).

The background to discovery is relayed by one of the researchers, Qian Wang, Ph.D., a professor at Peking University and an adjunct professor at VCU, who was dining in a restaurant in Beijing with her husband when she noticed artwork on the wall depicting pentagon tiles from the streets of Cairo. 'I told my husband, "Come, see! This is a pattern composed only of pentagons,'" she said. "I took a picture and sent it to one of my students, and said, 'I think we can make this. It might be stable. But you must check it carefully.' He did, and it turned out that this structure is so beautiful yet also very simple."

The researchers' paper, ‘Penta-Graphene: A New Carbon Allotrope’, will appear in the journal Proceedings of the National Academy of Sciences, and is based on research that was launched at Peking University and VCU.

7. Escher-like Cairo Tilings (2), by Alain Nicolas and Angie Leslie

Some excellent Escher-like instances by the French artist, Alain Nicolas, and Angie Leslie (in the form of a jigsaw puzzle), of ‘Curious Minds’, based on the Cairo tiling. Other contributions are sought.

Angie Leslie, of ‘Curious Minds’

Another, so far unique instance, is that of an Cairo Escher-like puzzle, of fish, by Angie Leslie of the US company ‘Curious Minds’, who specialise in creating unique educational learning toys for toddlers and preschoolers. These are commercially available, at the above address. (Note that this company is not to be confused with another of the same name, in Australia). To make clear the Cairo tile aspect, I have overlaid suitable lines. As such, this is the first such instance of a Cairo puzzle Escher-style,

8. Ceiling Panels (3), of Davos Congress Centre, Switzerland; Ghemlamco Arena, Belgium and Tamara Lebanese Bistro Restaurant, Cairo

Davos Congress Centre, Switzerland

A significant sighting and indeed magnificent is at the well-known Davos Congress Centre, Klosters, Switzerland, opened in 1969, and the venue for world economic forums since 1971. The centre has subsequently undergone major transformations and extensions in 1979, 1989 and 2010. The 2010 extension saw the Cairo tiling installed as a honeycombed suspended ceiling at the new plenary hall (which is itself pentagonal) with a 1,800 delegate capacity. The lighting of the room, coming from inside the panels, makes the concrete structure have a very light appearance, as if the ribs they were floating, and making them look like mere decorative elements. The architectural style of Davos, with its famous flat roofs, echoes the installation. The cost of the build was 40 million Swiss Francs (£32 million). The hall was designed by Basel, Switzerland architects Degelo Architekten, founded by Heinrich Degelo. However, little, if anything, is known as to the background to this installation; the website has merely bare-bone detail (and without reference to the Cairo tiling), although a like presentation is seen throughout the site on other projects, and the architects did not answer my mail asking for more details. That said, this is discussed by Beatriz Fernández García, of the Universidad de Valladolid, Spain, where García asserts or at least implies, foreknowledge of the Cairo tiling by the architects, and so I will thus take this at face value the awareness of the architects. For the mathematical tourist, it is not entirely clear if the hall (and indeed the building at large) is open to the casual visitor. If any reader does visit, do tell me if this is visitable or not!

Although it’s most unlikely, would any reader have details to add to the above?




Of the architect, Degelo Architekten is a Swiss architecture firm founded in 2005 by the architect Heinrich Degelo, born 1957. It has won many awards.


Geographically, Davos is a winter and summer resort village located in the heart of the Graubünden in the east of Switzerland. In the early 1990s, Davos became famous for hosting the World Economic Forum, an annual winter gathering of international politicians and financiers who represented a transnational elite. Together with the nearby town of Klosters, Davos offers a wide variety of winter sports activities, and summer hiking trails, set amid stunning Alpine scenery.

Ghelamco Arena, Belgium

The Ghelamco Arena (began 2010, completed 2013, and named after the constructor), of Ghent,  Belgium, a multi-use stadium (especially of the football club K. A. A. Gent), has a notable instance of the Cairo tiling, of modular pentagonal ceiling panels with acoustical sound absorption properties. This was designed by Mac Stopa of the Polish architectural practice Massive Design (founded 1996). The developer of the Ghelamco Arena, the Belgium company Ghelamco NV, commissioned Massive Design to provide the interior design for 20,000 sq. m. (200,000 sq. ft.) of the stadium’s interiors, including floor finishes, ceiling and lighting design. The Ghelamco Arena project also won an Interior Design Best of Year Honoree Award 2013 in the public space category. The modular pentagonal ceiling panels, of a ‘loose’ Cairo-tiling arrangement, have acoustical sound absorption properties, whose shape resembles the classic geometry of the stitched panels of a soccer ball. Approximately 10,000 Ecophon boards were cut to size and shape custom-designed by Mac Stopa.


© Mac Stopa

Stopa can undoubtedly be described as an enthusiast of the Cairo tiling, having used it extensively in a variety of architectural projects, great and small. (Another instance is at the Warsaw Spire Complex, Poland, and on clothing and wallpaper too. In addition to the orthodox presentation, these also involve variations of the design, where warping is evident.) However, there is no mention of the connection as to the Cairo association is made on the site and elsewhere, and so whether the use of the Cairo tiling is purposeful or accidental, the latter in the sense of a generic pentagon tiling is unknown. But Stopa must surely unaware of this association. Indeed, it may very well be stated, but if so among the vast amount of writings/publicity available on this project I have not been able to find this. 


I have previously contacted the practice (of 2015) in regards of the Ghelamco Arena, Ghent, Belgium, and of which although I received a polite and helpful reply, this was relatively brief, and would appear likely to have been overseen by office personnel rather than Stopa himself. My email primarily concerned photo permissions, rather than matters of his knowledge of the Cairo tiling as such, although I did mention the Cairo tiling by name. I should have been more specific! Although it would indeed be interesting to hear more details why he favours the Cairo tiling so much, in the light of this reply I have decided not to pursue further queries.


Background

Mac Stopa is an award-winning architect and designer, whose work spans several design disciplines: architecture, interior design, industrial design, art, graphic design and fashion. He is known for designing modern, innovative and functional interiors that reflect and enhance a company’s corporate image. The practice has won 66 international design awards. It is stated that he has an interest in mathematics and geometry. He seems to have acquired a degree of fame, with many published articles on him and interviews. He has an extensive social media presence on Facebook and YouTube. Stopa (and his wife, Dana) both seem to be lively characters, with their designs modelled by themselves on (colourful) clothing. He is also an electric guitar player and a music composer!

Tamara Lebanese Bistro Restaurant, Cairo
Some interesting and indeed novel use is to be seen at the Tamara Lebanese bistro, in Cairo, with numerous geometric patterned panels suspended from the ceiling, one of which includes the Cairo tiling. Such an instance gives credence as to its being a traditional Islamic tiling, although there is scant evidence of this. Upon enquiring with the company, of a Lebanese premise, on the possibility of these being from the Lebanon, they told me that these were simply generic Islamic designs.

'Bretzel Love’ Café Chair, Paris, France
A ‘Cairo Café Chair’, as seen in Paris, France, from the ‘Bretzel Love’ Café chain. The background of this as to the designer and manufacturer are unknown. However, the chronology is roughly known; it appears to be ‘fairly recent’, the chain having opened in 2009. Of note is the interlinking structure, reminiscent of Rinus Roelofs’ work. With my thanks to Robert Ferréol, of France, for drawing this sighting to my attention.

An interesting sighting, the first of its type, comes from the world of fabric/clothing, with a Kimono by Moriguchi Kunihiko (1941-), of Japan. This was a part of an exhibition on Kimonos at Paris in 2016 from November 16 to December 17, 2016, at the House of Culture of Japan to Paris. Kunihiko is a household name in Japan and has acquired a degree of fame, described as a ‘living treasure’ of Japan.

17. Canopy (1), Maple Leaf Square, Toronto, Canada

A pentagonal tiled canopy (inspired by the experience of walking through a forest’s dappled light) by United Visual Artists (UVA) a London-based art practice, of a 90-metre long light sculpture spanning the front facade of the Maple Leaf Square building in Toronto, Canada, of 2010. Their form, abstracted from the geometry of leaves, reflect nature. Whether the designer was familiar with the Cairo tiling is unclear; it is not mentioned on their web page, and a mail asking for further details to UVA went unanswered. Of note in the panoramic view is the famous landmark the CN Tower in the background.

19. Wine Racks (1), by Grassi Pietre, for Zýmē Winery, San PietroItaly

An unusual, and indeed unique instance, is by Grassi Pietre architects, for Zýmē Winery, of San Pietro, Italy, with the pentagons used as series of wine racks, in stone, with the wine bottles stored in a vault in a cave, as temperatures must remain constant. The use of pentagons is predicated on the logo of the company, of a wine leaf in the broad shape of a pentagon. Each pentagon measures 78 x 56 x 60 cm and weighs 85 kg.

20. Origami (2), Ron Resch - Folded Paper

Ron Resch (1939-2009) was a renowned artist, computer scientist, and applied geometrist, known for his work involving folding paper, origami tessellations and 3D polyhedrons. He famously designed the ‘Vegreville egg’, the first physical structure designed entirely with computer-aided geometric modelling software. Among his folding paper creations was a Cairo tiling, of a ‘folded mosaic’ titled ‘Bar-Bell Yellow’, possibly of 1963. For this, and other paper foldings of his, see:
http://www.ronresch.org/ronresch/gallery/extreme-paper/
The origamist Mitya Miller, an enthusiast of Resch’s work, and who has helped restored his site, has also folded many examples in the Cairo tiling style, see:

The stand, under the auspices of architects Werner Sobek, Fritz Mielert and Stefan Neuhäuser, was created to display the work of five young designers at design fair Blickfang in Stuttgart, in 2009.
    Disappointingly, upon asking for picture permission and more details the architects did not respond, hence the lack of pictures, although the link above discusses this in more than sufficient detail.

26. Acoustic Walls (2)

Fluffo, Poland

Fluffo, of Borzecin Duzy (near Warsaw), Poland, founded in c. 2014, is a relatively small company who describe themselves as a manufacturer and supplier of acoustic wall panels, of flexible, dense polyurethane foam, with the finish resembling velvet. They have an extensive website in Polish and an English option but is not searchable and a social media presence on Facebook, Pinterest and Instagram. They market the Cairo tiling (of a ten-panel range) as ‘Fluffo SOFT’, as wall panels only. The range is described:

Fluffo SOFT is a collection of decorative, soundproofing wall panels, available in a wide selection of colours, shapes and thicknesses. They soundproof a room in a beautiful and stylish way. With Fluffo SOFT you can enjoy a cosy, quiet and most importantly, beautiful interior.

This is primarily marketed in Poland, available directly from themselves or distributors as well as other European countries, but only as a token presence; the UK has only one supplier. The Cairo tiling is titled, curiously, as ‘Chain’, without reference to a pentagon tile (as an aside, quite how I found this is a mystery!), albeit is not strictly of a single pentagon, but is rather fused, of a (slight) incline, albeit differentiated by colour. It is available in 52 colours, of four blues, four yellows etc. The angles and side lengths are not stated, although the height and width are, 367 x 550 mm, with a thickness of 20-50 mm. It is not known when the Cairo tiling was introduced into their range. Given the widespread nature of the company, one would expect the tiles to feature in many homes, not just in Poland, but if so I have not seen any; all I have seen are as marketed, or supplied, by the company.

 

No mention of the connection as to the Cairo association is made on the site, and so whether the use of the Cairo tiling is purposeful or accidental, the latter in the sense of a generic pentagon tiling is unknown. Likely they are unaware of this association.

I did not contact the company, judged that they would likely not respond, fairly or unfairly, of a non-commercial query.  

Company details and background Fluffo, of whom the founder’s name and exact date (from a start around 2012 before a company as such about 2014) remain unclear, make a great play on that the panels were invented, designed and produced in Poland. The work, originally in their garage, on the implementation of their first collection of panels, mastering the technology processes and the creation of Fluffo marketing took almost 1½ years. The main part of the production process is done manually. The technological process – even though known for decades – is extremely difficult to automate. Since the founding, they have produced over 200,000 panels. The number of employees is not stated. No other relevant detail is given.

Kamilla Lang Hermansen, of Norway, a trainee architect at mmw architects (at least of 2008) together with the young designers at StookeAustad and the wood manufacturer Bosvik created what is described as ‘acoustic walls’. The walls were created for the exhibition at Beyond Risør in June 2008.
    Disappointingly, upon asking for picture permission and more details to Hermansen there was no response, hence the lack of pictures.


27. 'Pentagonal Framework' (1), by Adriel Designs
http://www.charterworld.com/news/adriel-design-introduces-yacht-project-lumen-oceanco

An interesting, and unique instance, is of a ‘pentagonal framework’ interior, on the 90m luxury motor yacht ‘Lumen’, designed by Adriel Designs, of the US, an interior design firm, for the prestigious Dutch luxury yacht builder oceAnco, although the exact circumstances as to the installation are a little hazy. John Cantu, of Nautlis3D, is also seemingly involved in the project. Upon seeking more details, a mail to Adriel Design went unanswered, although Cantu responded. Unravelling the somewhat tortuous background with so many people and institutions involved is a task in itself, and of which I largely refrain from! This being so, the background details here are subject to revision. More details are given at the link above.

28. Board Game (1), ‘Cairo Corridor’ by Markus Hagenauer
https://www.boardgamegeek.com/image/1566138/cairo-corridor

Another unusual instance is that of a board game, titled ‘Cairo Corridor’, by Markus Hagenauer, of Germany. This is commercially available, at Nestorgames, under the auspices of Néstor Romeral Andrés:
http://www.nestorgames.com/#cairocorridor_detail
And is described:
Cairo Corridor is a non-disconnection-and-area-control abstract strategy game for 2 players. In Cairo Corridor players alternate turns placing their pentagonal pieces in a board with a Cairo pentagonal tiling, trying to get the majority of pieces of their colour adjacent to a path that's being built during play and that connects the 4 sides.
The pictures show the game overall, in detail and Markus playing at the Nestorgames booth at Essen, Germany, 2013. (A major, annual four-day board game trade fair.)

David Mitchell, who lives in Cumbria, UK (and is not either the novelist or the comedian of the same name!), has made a feature of incorporating the Cairo tiling in his paperfolding design work. In particular, see the dedicated piece on the Cairo tiling on his website ‘Origami Heaven’:
http://www.origamiheaven.com/pdfs/cairotile.pdf
Further, he has various books and articles on origami to his name, starting with Mathematical Origami, of 1997, and Sticky Note Origami, of 2005 of which below shows a Cairo tile instance taken from the latter.

JAB Anstoetz Group, of Germany describe themselves as ‘medium-sized family business that has stood for stylish living and been associated with precious fabrics since 1946’. The size is somewhat of an understatement, as the company employs 1,300 people! Their products range from sunshades, wallpapers, floors and furniture. They have a searchable website. They market the Cairo tiling as a fabric simply titled ‘Penta’ (a common description, often seen in floors and wall tiles)’, 100% polyester. This is available in three colours, or is at least stated as such; the page merely asserts this but does not show. This is easily available, with worldwide distribution; there are over 100 outlets in the UK alone. I must admit, despite such a widespread presence in the UK, I had never heard of them until now! It is not known when the Cairo tiling was introduced into their range.


No mention of the connection as to the Cairo association is made and so whether the use of the Cairo tiling is purposeful or accidental, the latter in the sense of a generic pentagon tiling is unknown. Likely they are unaware of this association. The angles and dimensions of the tile are not known.

I did not contact the company, judged that they would likely not respond, fairly or unfairly, to a foreign, non-commercial query.  

Company details and background

Josef Anstoetz writes the first chapter of the company history. Under the name JAB – the abbreviation for Josef Anstoetz Bielefeld – the merchant uses his affinity for textiles and in 1946 opens a wholesale company for decoration and upholstery fabrics. After just three years the business is so successful that the rented premises in the "Spinnerei Vorwärts" have become too small. To enable further expansion the company moves to Rohrteichstraße 35a. The year 1955 is overshadowed by the sudden death of Josef Anstoetz. As his successor, Heinz Anstoetz takes over the management of the flourishing company. In 1959 the foundation stone is laid for a new building in Bielefeld-Oldentrup. Potsdamer Straße 160 becomes the new headquarters of JAB. The first showrooms are opened in Germany. In 1961 the focus is on the systematic development of the export market. The high-class home textiles and upholstered furniture of JAB also arouse great interest beyond the German borders. With the opening of JAB International Furnishings in 1979, the family business establishes itself in the British interior market. In 1996 Heinz Anstoetz celebrates his 50th company anniversary and then retires from operational business life. After his death in 1998, the company is renamed JOSEF ANSTOETZ KG. A series of takeovers and acquisitions continues in the 2000s and to the present day. The company continues to grow and now employs 1,300 people.

36. Panels, Laminam Star Maker, by Mac Stopa of Massive Design, Poland

The somewhat curiously named ‘Laminam Star Maker’, by Mac Stopa of the Polish architectural practice Massive Design (founded 1996), is described as a ‘quartz-based panel’, and makes use of the Cairo tiling as ‘small elements’, so small that from any distance that they are not discernable! This is described as:

Laminam Star Maker is a three-dimensional puzzle made up of pentagonal stars, built into a larger-scale, hexagonal tessellation

However, as such, it's not a puzzle in the conventional sense and there are no stars (or at least as I can tell)! 

The panels are 100cm x 300cm, which can be divided into three modular 1m x 1m tiles. By moving or turning adjacent tiles (as seen in the video below), many multiple geometric expressions are achieved. These large, thin and perfectly flat stain-resistant quartz panels are ideal for floors, walls and stairs in public areas and in residential projects and for both indoor and outdoor applications, including elevations in large scale architecture. The Laminam Star Maker slab won the highest award in the Red Dot Award: Product Design 2016 competition (called as the Oscars of Design). The Red Dot jury granted this product the most prestigious ‘Red Dot: Best of the Best’ award. The winning product has been developed in cooperation with Laminam Poland, who manufacture the panels. The first building in which the Laminam Star Maker slab was used is the modern office complex Warsaw Spire, Poland (see ‘As Architecture’ page).


As to technical matters, Laminam sintered quartz is a composition of natural materials, and in particular quartz, shale clays, granite rocks and ceramic pigments. Granules from the above raw materials are first pressed. Then, innovative sintering granulate is used, which is fired at a temperature of 1220 degrees. This method creates large-format Laminam boards that are perfectly flat and can be cut to a specific size with very high accuracy.

Stopa can undoubtedly be described as an enthusiast of the Cairo tiling, having used it extensively in a variety of architectural projects, great and small. (Another instance is at the Ghelamco Arena, Belgium), and on clothing and wallpaper too. In addition to the orthodox presentation, these also involve variations of the design, where warping is evident.) However, there is no mention of the connection as to the Cairo association is made on the site and elsewhere, and so whether the use of the Cairo tiling is purposeful or accidental, the latter in the sense of a generic pentagon tiling is unknown. But Stopa must surely unaware of this association. Indeed, it may very well be stated, but if so among the vast amount of writings/publicity available on this project I have not been able to find this. 

I have previously contacted the practice (of 2015) in regards of the Ghelamco Arena occurrence, and of which although I received a polite and helpful reply, this was relatively brief, and would appear likely to have been overseen by office personnel rather than Stopa himself. My email primarily concerned photo permissions, rather than matters of his knowledge of the Cairo tiling as such, although I did mention the Cairo tiling by name. I should have been more specific! Although it would indeed be interesting to hear more details why he favours the Cairo tiling so much, in the light of this reply I have decided not to pursue further queries.

About Mac Stopa Mac Stopa is an award-winning architect and designer, whose work spans several design disciplines: architecture, interior design, industrial design, art, graphic design and fashion. He is known for designing modern, innovative and functional interiors that reflect and enhance a company’s corporate image. The practice has won 66 international design awards. It is stated that he has an interest in mathematics and geometry. He seems to have acquired a degree of fame, with many published articles on him and interviews. He has an extensive social media presence on Facebook and YouTube. Stopa (and his wife, Dana) both seem to be lively characters, with their designs modelled by themselves on (colourful) clothing. He is also an electric guitar player and a music composer!

About Laminam Laminam is a producer of large format plates made of sintered quartz. The company was founded in 2001 (by whom is not stated) and for several years has built an extremely strong position in the broadly understood ‘home and interior’ industry. Its products are known all over the world, and for several years the brand is also present in Poland. In Warsaw, you can visit the only Italian showroom in this part of Europe.

37. Pouffe, by Patrica Lascano, Argentina

Patricia Lascano of Argentina has a self-named design studio of which she markets a variety of interior design items, including seats and chairs. She has a website and a social media presence on Facebook and Instagram. She markets the Cairo tiling (or what appears to be) as a pouffe (a cushioned footstool or low seat with no back). The pouffes themselves are evidently (from the images) designed to tile, which is a pleasing feature, although of course serve as single (utilitarian) furniture in themselves. 

Little detail is given on Lascano’s site and is without any reference to a pentagon, and what detail is given is largely inconsequential. She states:

Terron. Inspired by mathematic paterns (sic), these pouffs offer a number of different design combinations and could also create a infinite surface.

‘Terrón’ translates to ‘lump’ or ‘clod’, with another meaning as ‘cube’. Possibly this is  a sideways reference to pouffe lost in translation. 

This is also described as the ‘Deseo Project’ but quite what this is unclear. A search on this term gives ‘child sponsorship’. Elsewhere, on external sites, the pouffe is described as ‘penta tesela’.

   
Pouffe, left, and as a tiling, from above, right

As alluded to above, it is not entirely clear if the tiling here is of a Cairo tiling, but it is hard to be sure; the pattern (fabric) appears to be ‘stretched’, and so thus distortions arise. Strictly, upon closer observation likely not. An individual pouffe can be seen to echo the pentagon in outline (and is a nice feature in concept), and of which, seen at this larger, ‘undistorted’ scale, this is thus not a Cairo tiling. That said, if not it is obviously related to the Cairo tiling, with the ‘secondary’ hexagons (consisting of four pentagons) at right angles in a typical Cairo manner, and so I have thus decided to include here.

This is primarily marketed in Argentina, although exactly where is not clear! Possibly they are available from ‘Wide’, with ‘Widestore’. It is available in two colours, yellow and dark grey. The angles and side lengths are not stated. It was introduced into her range in 2015.

No mention of the connection as to the Cairo association is made on the site, and so whether the use of the Cairo tiling is purposeful or accidental, the latter in the sense of a generic pentagon tiling is unknown. Likely she is unaware of this association.

I did not contact Lascano, of which although as an individual I would more likely receive a reply than a major company I decided not to bother.

Design Studio details and background Patricia Lascano describes herself as an industrial designer since 2001. Her designs are produced and commercialized in Argentina and Brazil. Her products have several awards and some of them are part of the Argentine Design Collection of the Museum of Modern Art in Buenos Aires MAMbA. No other relevant detail is given.

38. Wall Art, by Pier Paolo Spinazzè, Italy

Pier Paolo Spinazzè, of Italy, an artist and designer who describes himself as a wall designer, makes extensive usage of the Cairo tiling as wall art. He has a website, albeit primarily he is more prominent on social media with Facebook. Oddly, despite an undoubted interest in the Cairo tiling (and indeed other pentagon tilings), although the Cairo connection is acknowledged (although incorrectly, with ‘souks’) this is not detailed as such on his site or Facebook page. 

As alluded to above, many instances can be seen, of which perhaps the most impressive is that on a Beetle car. Other instances include the company MGM Minerbe and at Veronafiere SpA - Fiera di Verona

I contacted Spinazzè, of this 2019 inclusion (with a translation), and previously, but he did not respond to requests for photo permissions and specific background details.

Background Pier Paolo Spinazzè, born 1982, has since 1998 dealt with the creation of murals, street art, and graffiti, a passion that he has been able to turn into work. No other relevant detail is given.

39. Wall Art, by Joseph Warren

An instance of wall art, titled ‘CAIRO’ (capitalised as in the original), of which determining the originator and background is not easy, and of which the story is decidedly tiresome to unravel, with scant detail available and much obfuscation. Therefore, the text below is subject to revision. That said, from what little detail there is, or can reasonably be surmised, the designer appears to be Joseph Warren, of the UK, whose name is associated with this on the commercial Saatchi Art site (the world’s leading online art gallery). The art is titled ‘CAIRO No. Eighteen No. 1’ (as according to the number of tiles), of the inflated price (of which Saatchi is renowned for) of £743! It would indeed be interesting to know if this sold! This is described as:

Installation: Paint, Enamel, Stencil on Steel. One of a series of unique painted steel artworks.

CAIRO artworks are inspired by the tessellating pentagonal tiles found on pavements in the Egyptian capital. Exploring a modern industrial aesthetic, CAIRO pentagons are formed from steel and copper, and given a playful variety of surface treatments. The result is a collection of striking, three-dimensional geometric artworks with endless permutations, and timeless appeal.

Fits to wall with magnetic fixings which are included.

The wall art is also marketed on the commercial site ‘Image Surgery’ (seemingly related to Saatchi).  This is described as:

CAIRO Four Nº1 £120.00 (but out of stock as of this 2019 writing)

Three-dimensional geometric artwork inspired by the tessellating pentagonal tiles found on pavements in the Egyptian capital.

CAIRO is a series of artworks inspired by the tessellating pentagonal tiles found on pavements in the Egyptian capital. Exploring a modern industrial aesthetic, CAIRO pentagons are formed from a variety of materials and given experimental surface treatments. The result is a collection of striking, three-dimensional geometric artworks with endless permutations, and timeless appeal.

CAIRO artworks are supplied with concealed magnetic wall fittings for invisible mounting. The designer, presumably Joseph Warren, is thus aware of the Cairo association, and so the use of the Cairo tiling is purposeful here.

Saatchi, left; Image Surgery, right

Apparently, the art was exhibited at London Design Fair, possibly of 2017, from a Joseph Warren Twitter retweet, although details here are next to non-existent; I was not able to find the reference on their site.

The Saatchi and Image Surgery sites show different versions. On the Saatchi site, the tiles are coloured curiously, within an overall blue, green and black premise, with single pentagons of blue, green and black and other tiles with arbitrary divisions and circles. The Image Surgery site has single pentagons of blue, red and orange and black and white stripes, with geometric symbols overlaid, of an arrow, equilateral triangle a U shape and circles, all in contrasting colours. Both colouring schemes are arbitrary and baffling!

I did not contact Image Surgery, Saatchi Art or Joseph Warren. I judged that Image Surgery and Saatchi Art would not reply, and as for Joseph Warren I simply gave up; he obviously doesn't want to be contacted, detailed below! But why be active on Twitter? It is all most strange. Each to his own...

More than most entries here, this entry, of various trying aspects, is undeserving of my time and largesse. But there you go; it is now documented.

Background

Joseph Warren

Warren himself, presumably a designer of sorts, is somewhat of a mystery! The only details given on his Saatchi page are his location, namely Colchester, Essex, United Kingdom! His Twitter page likewise gives no detail and is without contact details! No other relevant detail is given.

40. Wall Art (3), of 'Litton Lane' Range

An instance of wall art, from the ‘Litton Lane’ range, of two pieces titled ‘Yellow and Brown Wooden Honeycomb Wall Decor’, 28 in. x 28 in, for $57.42, and ‘Rustic Geometric Patterns Wooden Wall Decor in Stained Brown’, 35 in. x 35 in, for $76.00. This is available from The Home Depot, US (the largest home improvement retailer in the United States, although unknown in the UK) and likely other outlets too, as Litton Lane is frequently mentioned, although I have not found more instances of the Cairo tiling art here. This is respectively described as:

This square wall art made of Chinese fir wood and MDF features a geometric pattern of interconnected pentagons in black, brown, and gold that complement shabby-chic-inspired design themes. The simple, geometric design and square frame of this wall art blend well with modern-style theme settings. This wall art comes in distressed colors and finishes that add a distinct rustic vibe to interior design themes.

and

This wall plaque features geometric-shaped accents crafted of fir wood. It features distressed brown, yellow and white finishes that will look great on your rustic and traditional home settings. This decorative piece is enclosed in a sturdy wood frame with a distressed brown finish that can be hung easily on your wall.

Oddly, both instances list just three colours, but this is incorrect, each instance has four colours; a light brown and blue colouring were inexplicably omitted here.


No mention of the connection as to the Cairo association is made on the Home Depot page and so whether the use of the Cairo tiling is purposeful or accidental, the latter in the sense of a generic pentagon tiling is unknown. Likely the (non-stated) designer is unaware of this association as this would have otherwise have been stated. A curiosity here is that the ‘Yellow and Brown…’ instance has a picture that is not a Cairo tiling as such, as the angles here are clearly not 90°, albeit close. Likely, given the true Cairo tiling, the (non-stated) designer misrepresented the Cairo tiling. Whatever, uncertainties aside, as this nonetheless is very much as a Cairo tiling in appearance, I have thus decided to include, of which I describe as a ‘near miss’.


I did not contact The Home Depot, judged likely that from a major conglomerate I would not receive a reply. 


Background Details

Litton Lane is apparently a title given to a wall art range, of which The Home Depot gives 107 items. As such, I was unable to find any more detail on the name.


The Home Depot was founded in 1978 and is the largest home improvement retailer in the United States, and indeed the world, supplying tools, construction products, and services.
