also it works great with OSA Kit (web browser plugin), if you search the forum you can find a couple of projects using it.
Also there is this guy Mic (he is actually in the game development industry) that has a really great project of destructible vehicles
ragdoll youtube video my arcade racer big-ass HDTV test with bump, specular, bloom, blur, etc...
MIc's destructible car test check out his videos for more recent versions.
I believe he had this demo in playable form somewhere.
