Eager to be freaked right on out? If so, head past the break and mash play. There, you'll see a recent demonstration by Tohto C-Tech, where a 3D camera setup was used to capture a person's face and then reproduce it on a monitor (in 3D, no less) in real-time. Engadget are told that an undisclosed GPGPU setup was used to pull it off, as typical CPUs just weren't quick enough to render the final product on their own. The camera setup actually captures the face from two different viewpoints, enabling the sides of the face to be shown in addition to the front. Engadget warned you that copious amounts of freaky were involved.
