Microsoft Kinect powers DIY Eye of Sauron
Microsoft's Kinect has been wielded for numerous applications, but now it has been used to create a giant eyeball that follows you round the room.
The team at The Technology Studio put this homemade Eye of Sauron  together using a Kinect, a PC and a Puffersphere.
The Puffersphere, a spherical display system  from the company Pufferfish, was loaded with the eye image and readied to rotate with the help of Windows Presentation Foundation (WPF) software.
Of course, we all know about Kinect support on a PC , and with that and "natural interaction" middleware OpenNI , the team were successfully using the tracking information from Kinect to rotate the eye image projected onto the surface of the Puffersphere, making the giant eyeball appear to move.
Pretty clever, pretty creepy and pretty frikkin' awesome if you ask me. Now if only they could make it turn off when you remove your ring... ®
