A very cool application - Face Demo(Facial Reflectance Field Demo) by Chris Tchou and Dan Maas. Developed at the USC Institute for Creative Technologies.
This demo allows you to virtually relight real faces. You can light the subject as if they were in a variety of real lighting environments captured from around the world, or position and adjust your own virtual lights to achieve whatever effect you desire.
