Check out this cool display and interface with Google Earth:

Holographic Google Earth from Nicolas Loeillot on Vimeo.

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. via Google Earth Design
