My first attempt at a facebook game using the physics behaviour, took some time to work out the kinks, still have a few kinks left to fix up:
apps.facebook.com/stophittingyourself
I don't have a facebook account. Any other way of viewing the game?

Sorry, only on facebook at this time. I teach Computer Science at a high school, and this was my demo game to show how to build a facebook app. I'll probably do a kongregate version down the road.
