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.
rickruss2013@packersmoversdelhi Thanks! If you like this one, take a look at the Inversion of Truncated Octahedra, Inversion of Cuboctahedra, and Eshchers Solids filling space...you might like those as well.
rickruss2013 @galiliosharma@galiliosharma The difference is just that the polished brass is more shiny. Click on both renderings to see the difference. But the polishing process used at Shapeways does not polish the inner surfaces. To do that, you would have to tumble the model with small steel balls.
