Sphere, Heart, and Cube

Here are a sphere, heart, and cube made from a polyhedron containing 380 hexagonal and 12 pentgonal faces - a polyhedron related to a 780 atom Buckyball. The same edges, (bonds), are used for all three objects. The polyhedron vertices form an approximate sphere which is mapped to a cube http://stackoverflow.com/questions/2656899/mapping-a-sphere-to-a-cube and to a heart. The heart is made by sending the x,y,z coordinates of the sphere to x, y+fx*abs(x), fz*z where fx and fz are adjustable parameters. The method was suggested by DJ Moews. OpenSCAD code is included.
