A rhombic triacontahedron
A rhombic triacontahedron: the faces are rhombi that are all the same, that meet in vertices or at 3 to 3 or at 5 to 5. It is the dual of the uniform polyhedron (3,5,3,5). There are lamps that use this structure. This is a similar model.
This picture has been used for the posters on polyhedra for the exhibition Simmetria, giochi di specchi - Symmetry, playing with mirrors.
