If you thought Steve’s demo of Multi-Touch on the iPhone was impressive, you need to see this TED talk from Jeff Han, who is a research scientist for New York University’s Courant Institute of Mathematical Sciences. Get the feed or download a zipped copy of the QuickTime file.

This is multi-touch gone crazy. The keywords that grab me are “low-cost”, “scalable” and “high resolution”.

This is a must-see.
