So I wikipedia-ed mathematics and art, and found something kind of interesting about platonic solids and polyhedrons being used frequently in western art.  "In geometry, a platonic solid is a regular convex polyhedron.  These are the three-dimensional analogs of the convex regular polygons...They are unique in that the faces, edges and angles are all congruent" (wikipedia).

These shapes appear in, to name a few,  Dali's "The Last Supper", da Vinci's book The Divine Proportion, and Albrecht Durer's "Melancholia".
