According to a recent theory the Universe could be a dodecahedron. It is surprising that Plato used a dodecahedron as the quintessence to describe the cosmos.
Plato believed that mathematics provided the best training for thinking about science and philosophy. The five regular solids are named Platonic Solids today after Plato.
Of the 5 solids, the tetrahedron has the smallest volume for its surface area and the icosahedron the largest; they therefore show the properties of dryness and wetness respectively and so correspond to Fire and Water. The cube, standing firmly on its base, corresponds to the stable Earth but the octahedron which rotates freely when held by two opposite vertices, corresponds to the mobile Air. The dodecahedron corresponds to the Universe because the zodiac has 12 signs (the constellations of stars that the sun passes through in the course of one year) corresponding to the 12 faces of the dodecahedron.
The posters visualize the five solids in space creating a surreal depiction of Plato's Universe.
