From TechEBlog:
Called Alter Ego, this software basically takes advantage of blend shapes to copy facial idiosyncrasies and produce emotive life-like 3D character animations. Its flexibility allows for the software to be used in real-time game cinematics, pre-rendered projects, and even game trailers.
This would be a bit like Poser (for those of you who’re familiar with this program) but in rendered videos instead of simply character poses. Nifty!
