Prof. Dr, Max Bruckner, Four Plates from the Book “Vielecke und Vielflache”, (1900)
Regular convex polyhedra, frequently referenced as “Platonic” solids, are featured prominently in the philosophy of Plato, who spoke about them, rather intuitively, in association to the four classical elements (earth, wind, fire, water… plus ether). However, it was Euclid who actually provided a mathematical description of each solid and found the ratio of the diameter of the circumscribed sphere to the length of the edge and argued that there are no further convex polyhedra than those 5: tetrahedron, hexahedron (also known as the cube), octahedron, dodecahedron and icosahedron.

Created out of plastic this interesting shelving system really messes with your mind. Simple to assemble and use, the different colours and angles makes it hard to comprehend what you’re really looking at. Is it flat or three dimensional? Can it even be used as a shelf? It really is hard to say when viewing it from the front.
