Integrating hpysics with Grapefruit might be a good topic for the Hackaton, trying to make a simple game (e.g. Pong or Breakout)
Be sure to have "more than two simultaneously moving collision objects besides paddles" in the specs, or it won't get close enough to a real physics simulation... well, at least I know how to get an A for a breakout by not allowing the ball to travel below the top of the paddle to hide a bug. Devastatingly simple vector equations get quite complex if you happen to stare at their assembly incarnations. -- (c) this sig last receiving data processing entity.
