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.

Jeppe Hein - Objects in the mirror are closer than they appear (2007)
“OBJECTS IN THE MIRROR ARE CLOSER THAN THEY APPEAR” shines behind a two-way mirror, merging the text with images of the visitors and the surrounding space. The text references the warning sometimes found on car side-view mirrors, alerting the viewer to the optical illusion of the altered field of view. The oversized scale of the phrase juxtaposed with the two-way mirror dares the viewer to take a closer look at what he or she sees, and to question the implications of the text in the apparent closeness of the reflected objects.
