Guys, I found this to be pretty interesting on the Havok website. ! This free physics  & animation engine  allows you to make sell and release (commercially) any game as long as you keep the distro price below $10.00.   Thought some ppl here might be interested in this for adding very kool graphics and physics to their games or projects.
The link is as follows:
