Interactive Cloth Simulation

I wanted to see if it was possible to build a physics engine that could model reasonably high-resolution soft bodies interactively and in real-time. By using a standard gaming GPU, I reached the point where testing the physics engine was kind of fun - so I thought I'd share.
Model: Victoria 7 from Daz
Dress: Evening Gown by Ravenhair (with modifications)
Scarf: Rectangle modeled by me ;-)
