Using Kinect to Track Facial Expressions?

Does anyone have any input on how you can perform facial tracking? I believe I saw a video of it somewhere but wasn’t sure if there was source code or futher information out there. Obviously there are many softwares and hardwares currently available but outside of my price range. I’d really love to get this moving somehow since its gotta be available somehow some way.

Once the SDK is out, i’m going to tweak a program for face recognition. Stay tuned!

i believe thats a mix of realtime point cloud capture and image rendering.
