Remember the 3D rotating Death Star from Star Wars?
Computer whizz Robbie Tilton has built an amazing hologram computer display controlled by Leap Motion 'mid air gesture' technology.
The display isn't actually 3D, but creates the illusion of depth by using a four sided prism to display linked computer images.
The result is a globe which appears to spin above the table.
The Leap Motion is a cheap box you can attach to your computer to control it without touching the screen.
By combining the two you can just about live your Tony Stark fantasies.
