"Starting next week, Mac users should be able to surf Google Earth using a Nintendo Wii Balance Board.

In a blog post, David Phillip Oster, a Google Earth iPhone engineer, explains that he created a program called Earth Surfer that can interpret Bluetooth data transmissions from a Wii Balance Board and can use that data to control navigation in Google Earth."

Now we only need to wait till google finds a way to predict a 3d image from sattelite imagiary or combine it with streetview and built a whole 3d model of the world. At least that was the first thing that I thought of when I saw the video.
