Everyone's going into the whole motion gesture thing now. Its a good thing, which sort of paves the thought that phones and other devices will be able to controlled by your gestures soon in the future. Apple,  has filed for a new 3D GUI patent making using an iPhone or iPad like how you'd use a cross between Windows and Kinect would be.

The patent is about an interface that would use proximity sensors to let a user control a "camera view" that would shift a 3D environment as the mobile device is rotated or moved. The interface can be controlled by gestures made above the screen.
