Two university software developers have cooked up a pretty clever use of the iPad 2's new front-facing camera: tracking your face to create the illusion of depth. It's not real 3D, but it's pretty damn cool looking.
It may not be the most practical graphical trick (the idea of 3D menus is barf-worthy), but for games and other visually rich apps, being able to "look into" your iPad could be terrific. And it's seemed like Apple is thinking the same thing, given their patent for similar tech a couple years back. [via MacRumors]
