A transparent computer has been revealed at the TED conference in Los Angeles, which allows users to reach through the screen.
Jinha Lee, a TED fellow and a student at Massachusetts Institute of Technology (MIT) has been working in collaboration with Microsoft to design the SpaceTop 3D computer.
It allows users to literally reach "into" their computer, and manipulate or move files and data with their hands.
The SpaceTop 3D features a transparent LED display and camera-monitored gesture controls to create the illusion of a box behind the monitor.
Lee said on his website:
The SpaceTop 3D is currently just a prototype and no consumer devises are currently planned. But it does provide a glimpse at what desktop computing could be like in the future.
