A GTC 2013 trailer from NVIDIA shows off "Face Works," some new technology they have created to render more realistic human faces. Word is: "NVIDIA Co-founder and CEO Jen-Hsun Huang shows a demo of Face Works technology running on the GeForce GTX TITAN GPU. It includes a must be seen to be believed, amazingly realistic simulation of a face in this second segment of the opening day keynote at GTC 2013." Thanks GamesHQMedia.
