How to 'reach inside' your computer

A graduate student at MIT has developed a 3D computer interface that enables users to apparently reach "inside" their computers to move documents and windows around using their hands.
The SpaceTop 3D desktop was demonstrated at the TED conference by Jinha Lee, who developed the system during and after his internship at Microsoft Applied Sciences.
