my bike tire wallet with drop impact alert--smacklights!

I made a wallet with impact-sensitive LEDs in it so that if I drop it, it lights up. Also fun just for smacking on things to make pretty lights. I'm writing it up as an instructable for instructables.com. In this video I shake the wallet to show that it only lights up on slight impact, not from motion alone. also, the wallet itself is made from an old mountain bike tire and inner tube.
