This is awesome. This was shown at this years CES. It's an 'unlimited touch point' screen. It features full HD resolution, and will be able to be hooked up to a PC for input. This thing sports some pretty impressive technology sporting a 46 inch screen with 12 inches of depth in order to provide sufficient space for the infrared cameras embedded in its back to capture the surface.
Take yours home for the low, low price of $17,000.
P.S. whenever I read 'MultiTouch', I actually read 'Multi Pass' out loud to myself. Am I alone?
