Link: Face-tracking and 3D Scene

Snapshot from the 3D Scene and Face tracking demo

I may be slow on the uptake here, but Mr.doob has some awesome HTML5 and Flash Player showcase pieces over at mrdoob.com. It's hard to pick a favorite, because they're all darn impressive, but I'm a fan of the Face-tracking and 3D Scene demo (which I've screenshotted above).  It's based in Flash, because it has to access the computers' webcam, and is a pretty neat concept.

If it didn't require the whole webcam-access notification message that makes the whole effect so obvious, I'd definitely want to slide this into loads of projects, just for the hell of it!
