Platonic Solids are regular polyhedron: eg. Tetrahedron, Hexahedron, Octahedron, Dodecahedron Icosahedron.
Many artists were also visually intrigued by the platonic solids too. This painting called _ The Sacrament of the Last Supper_ by Salvador Dali shows a huge dodecahedron (a twelve-faced Platonic solid in which each side is a pentagon).
