Real-time facial effects grant actors arsenal of a thousand faces

Sorry Saw and Nightmare on Elm Street fans, ‘facehacking' isn't quite what you're thinking. It could be just as exciting, though, and even alter the horror genre as we know it.

Facehacking combines face movement with 3D projection mapping in real-time. A projector casts an image onto a face while a tracker keeps that image fixed on the owner even while in motion. Think of it as a temporary tattoo made of light that can change on demand.

Enthusiasts of the face hacking found in slasher flicks can look forward to live performances with gore previously only reached by those with access to CGI and stop-motion photography. The impact on other kinds of performances is equally interesting. It was even seen at this year's CES show on the Intel stage.
