Wow that is really cool!

About the ragdoll demo. It's by far my favourite demo. But I noticed that when you flip and collide the puppets a bit too hard they'll start to spin so fast that they don't stop anymore.
I suppose it probably wont appear in a game. But I thought I should mention it nonetheless.

Also the charactercontroller demo doesn't work for me. When I start the demo I see something that looks like the first picture in the post above. But after about one second the screen goes all blue.
