Ecstasy Animation Tool by BrokeAss Games

ECSTASY is a dynamic motion synthesis program. What that means is it takes in character motions, either from MoCap or from wherever source, and it puts it on any character - all within a ragdoll physics enviroment!!! It gives you joint motors and ragdoll capability, and then it adds in some AI, and basic motions, for things like "get up" -- and then it gives you a big, red, record button to capture what you create.
