3D multitouch interface hinted by Apple patent

A recently-published Apple patent application suggests the introduction of 3D into some future multi-touch interfaces. Originally submitted on September 29th, 2008, the filing describes a graphical interface with 3D objects, and means of manipulating them using various gestures.
