I’m sure many of you have seen this already, but as I’ve found lots of friends hadn’t; here you go.

Jeff Han of New York University has develped as touch screen that can detect multiple touches at the same time. Not impressed? Take a look at the video: this allows for an inspiringly intuative new breed of user interface, with example applications allowing Minority Report style interaction.

The system uses FTIR (frustrated total internal reflection) of side lighting, and when one touches the screen this light is scattered away from the finger, and picked up by a camera underneath.
