Holographic Google Earth from Nicolas Loeillot on Vimeo.
How cool is this? Google Earth projected into the air as a 2D hologram? From the Google Earth Blog:
The technology comes from UbiqWindow and lets a computer screen be projected in mid-air. They have devised a touchless way to interact with the "hologram", and Google Earth is a great way to show off its capabilities. it's not a 3D projection, just 2D. But, it sure looks cool.
