Tromso students put together the best interactive display wall we've seen yet (video)

Take everything you thought you knew about multitouch and throw it out. Okay, keep the Minority Report stuff, but throw everything else out. What we're looking at here is a 22 megapixel display, stitched together from the output of no less than 28 projectors (7,168 x 3,072 total resolution), which just happens to respond to touch-like input in a fashion even Tom Cruise would find fascinating. You don't have to actually touch the wall, floor-mounted cameras pick up your gestures in 2D space and a 30-node computer setup crunches all the computational and visual data to deliver some buttery smooth user interaction. For demo purposes, the makers of this system grabbed a 13.3 gigapixel image of Tromso and took it for a hand-controlled spin. See the mesmerizing show on video after the break.
