Students at the University of Tromso in Norway have put together a ginormous interactive display wall.  The 22-megapixel display utilizes 28 projectors to spit out a resolution of 7,168 x 3,072.  It’s multitouch capabilities allow users to interact with the wall in a myriad of ways, Tom Cruise-style; gestures include hand swipes for panning and snapping fingers for zooming in.  And all of this can be down without actually touching the wall.  But how is that possible?  A number of floor-mounted cameras pick up your gestures in 1D and a 30 node computer setup manages to group together the various perspectives to determine 2D location.  In the demo video above, the wall outputs a 13.3 gigapixel highly detailed image of Trosmo.  Check it out and be blown away be its awesome power.
