Glasses free 3D from an iPad 2?  Tell me more!
Using some clever head tracking with the front camera, the iPad interprets the position and angle of your face to adjust the display.  The result is a realistic 3D effect for one viewer.  Clearly more than one viewer would be impossible.  If this technology demo turns into standard practice, it's almost worth getting one!
