Now this is pretty cool! I can only hope this is incorporated into Photoshop someday. A man by the name of Volker Blanz and his team have developed a software application in which they analyzed hundreds of facial images and built a composite mesh that can be used on virtually any photograph to build a 3D model. The model can then be manipulated to various facial expressions. This can be used to open and close eyes, make a frown or a smile, and even change the weight of a face by making it look bony or fleshy. It really is quite fascinating. Check out this video demonstration.
