Ball of Whacks magnetic creativity toy/tool

I gave "Ball of Whacks" to my 6-year-old son as a Hanukkah gift and I wish I'd have given it to myself. It reminds me a bit of Rubik's Snake but it's much more free-form and fun as the individual blocks aren't permanently connected but rather held together by 180 rare earth magnets. The blocks fit together in a 30-sided rhombic triacontahedron and can be recombined into animals, stars, and other geometric wonders. The Ball of Whacks comes with a guidebook suggesting lots of neat configurations, creativity exercises, and tips but we haven't bothered with that yet. It's addictive without any instruction. Ball of Whacks is available in red, blue, black, and multi-color which is what I, er, my son, was given. Maybe next we'll go for Von Oech's X-Ball, Y-Ball, or Star Ball magnet toys! Ball of Whacks
