This is a video of Face2Face, a program developed to add the real-time facial expressions of an actor to the face of someone else. The actor input video is captured via a standard webcam, and the results are surprisingly accurate. Obviously, this will be the basis of all future political smear campaigns. Plus, as Hedonistica pointed out, celebrity sex videos. The future is looking bright.
Hit the jump for the video. Also, inb4 'There's no need to fake anything Donald Trump says'.
Thanks to Josh, who agrees what a time it is to be alive.
