I tend to dip in and out of this project so 3 years for a reply is about par for me ;-) To answer your question, the solution works in both clockwise and anti clockwise directions as long as you’re consistent. I didn’t realize this at first and just assumed (I know, I know) that everyone would build...

Another update (Yes, I've been working on this on and off for many years). I finally gave up and fixed the dihedral angles so these tiles can really only make a truncated icosahedron. Each edge has 2 small magnets, North and South, so they go together with a very satisfying SNAP. I have created 5 di...

Just an update, still working on this. I tried tiles with magnets but was disappointed with the results, so I am updating the snap-together tiles and should have my next prototype soon. I upgraded to Great Stella and am still discovering the new features. My favorite so far is animated GIFs: https:/...

It's not really a model, but I've been using Small Stella for visualization as I construct a new type of crossword that is played on the surface of regular polyhedra. http://robotguy.net/puzzles/tn_trunc_ico_puz.png http://robotguy.net/puzzles/tn_polyhedra.jpg http://www.youtube.com/watch?v=c8Yt9iJU...
