rickruss2013 This is great, David, I'm glad Andy Blofield put me in touch with you, and for discovering this model. Are you using Mathematica also? I made a 20 cube compound by creating the same icosahedral symmetry with a dual of the octahedron. (www.shapeways.com/product/N5WBMQ2NU/20-cube-compound) This stuff is such fun, eh? Love your work!
rickruss2013 Hi, Camazine, This is a really neat model! What software did you (or Bathsheba) use to make it? I work only with Mathematica, Meshlab, and Blender so far, and am not sure I could create something like this with them.
