Welcome to the future bucky, it shure is purdy neat...
Sadly this was the first thought I had when looking at this page detailing and showing a video of a bi-manual, multi-point, and multi-user input on a graphical interaction surface.
It's incredibly neat but the video itself offers a much better explanation of what it is and does than I ever could.
:Edit: Site may be a tad slow, it seems to be getting raped.
Gang-banged is more like it. You're helping to defile an innocent website! You brute!
