Virtual faces

I've heard of green (or blue) screens before but not green faces ;)
A former apply guy has developed some pretty neat technology to help create better virtual faces based on the real ones.

Contour, a futuristic camera system that will add photorealistic three-dimensional effects to digital entertainment. The new system will be introduced today at the Siggraph computer graphics conference in Boston, and effects created with it could start appearing as early as next year.

The system could change the nature of cinematography in several ways, according to leading Hollywood producers and technologists who are planning to use the system. For example, it will make it possible to create compellingly realistic synthetic actors by capturing the facial movements of real actors in much greater detail than is currently possible.
