I bet you watched the movie Minority Report . Remember those cool gloves which let the guys easily access the images and all the computer menus? They were cool weren't they? And you guys thought we had to wait tens of years before we get something like those for reasonable amount of money, think again!
A pair of bright brains (Dan Phiffer and Mushon Zer-Aviv ), open source software, Google Maps API and two ping-pong balls with key chain LED lights drilled inside them adds a complete new dimension to user computer interaction! The tool is called Atlas Gloves...
By the way, did you also noticed that Google Maps is slowly becoming de facto tool for geographical imaging on big EV networks like CNN?
PS: Here is a video of the tool
