This is a TAT interface. TAT makes nothing but amazing interfaces. This one gives the illusion of 3D by tracking the orientation of the device and the position of the user's eyes. When the device tilts away from the user's plane of vision, the icons "drop" "shadows" to simulate distance from the background. It's all 2D, but damn convincing.
This is Grovers, "Near....Far!" in action.
