There's two great reasons to share this video:
1. It looks like the future of computers...
2. Great example of sponsored content (from BMW) and how to be useful to the network via YouTube... except for the cheesy ad at the end (but it's at the end so you don't have to watch it. I think a logo and a link start and finish would have sufficed).
Here's the description from YouTube:
Jeff Han is a research scientist for New York University's Courant Institute of Mathematical Sciences. Here, he demonstrates—for the first time publicly—his intuitive, "interface-free," touch-driven computer screen, which can be manipulated intuitively with the fingertips, and responds to varying levels of pressure.
