It seems like the multi-touch revolution that's happening right now is really bringing out the DIY'ers -- and this latest feat of hackery is right up there with the best of them. Christopher Jette has created a massive, 56-inch multi-touch display in his spare time using a box that resembles an old rear-projection TV, 168 infrared LEDs, and some serious elbow grease. The LEDs dot the perimeter of the screen and create a field of IR light which is scattered when touched, a webcam mounted at the back of the display picks up the movement and translates it to input. If you've got some time on your hands, there are instructions available for recreating the experiment, or you can just sit back and watch it in action in the video after the break.
