There are many ways to make intermediate forms between dual polyhedra. This was made using the expansion method. The faces of the cuboctahedron (red and blue) were moved outward, as were the green faces of the rhombic dodecahedron, until the meeting of all possible vertices. The yellow rectangles were the spaces created between faces by this expansion.

The polyhedron shown at the top of the page, the one based on a cube, an octahedron, and a rhombic dodecahedron, is quite lovely. I shall promptly construct a model of it and include a photo of it with my next post. I am glad to have visited this splendid web site and shall visit it often.
