Touchgrind: Multitouch fingerboarding for the iPhone
Pretty interesting, even if you're not up for doing something as silly as pushing a tiny skateboard around with your fingers. It looks kind of fun, actually -- flip your finger out at a certain angle with a certain speed, and the little board responds. I'm curious to see, however, if it's an actual physics engine (which would be awesome), or if it's just responding to certain gestures and then running prerecorded flips. The game's set to come out in October. We asked Illusion Labs about a price, but they said they hadn't figured it out yet.
