Math & Art & Puzzels

Not sure how this started but for a long time I found polyhedron (Geometric shape) nice to look at. At some point i started to collect puzzles that have nice shapes like polyhedron. But I collect any puzzle that has a unusually solution. Here you will find some of the stuff I made.

I bought a book from steward coffin and found a couple of nice puzzles. one of them i created with Inventor (that is a 3D drawing program) and let it print. if you like puzzles try to get a copy of this book it has a lot of tips for creating your own puzzles.
