Into thin airThis sorta reminds us of that 3D crystal ball that turned up a few months back, except with out the crystal ball. It's a prototype of a display from IO2 Technology called the Heliodisplay that can project a floating image into thin air that you can walk through. The press release compares it to that scene in Star Wars where R2D2 plays Princess Leia's distress message, so expect to see countless references to R2D2 in the mainstream media's coverage of this.
