Seems like Mr Gates cooking up some interesting stuff for all those Microsoft bashers. After Surface, check out Photosynth.

Photosynth takes a large collection of photos of a place or an object, analyzes them for similarities, and displays them in a reconstructed three-dimensional space. So who knows my Opera House Sydney photos on Flickr might be the next ;)

Its quite an experience when I tried it. But a higher system configuration recommended.
