Rag-doll physics in flash

Someone has created a rather mezmorizing flash animation. The rag-doll physics in the flash is really something to see. Almost relaxing to watch in a way.
Check out this animation: tetka. It’s basically an articulated model falling through some bubbles, but it’s strangely addictive. You can grab points on the model’s body and manipulate it, bending it in bizarre, contorted positions, and forcing it through small openings between the bubbles.
I wish I was that flexible.
