Microsoft: Teh Awesome
Even the haters have to like this stuff. (This one's better.) Photosynth stitches together photographs to form 3-D walkthroughs that are incredibly fun, useful, and cool. There are some amazing potential commercialization possibilities here, not the least of which is offering incredible street views along with mapping, distribution of the point clouds to interested industries (developers, video-game makers, etc.). Best of all, Microsoft needs only keep the processing and data centers churning. The footwork will be done by geeks and enthusiasts like me.
This tech was one of the reasons I was really hoping Mr. Softy would get Flickr via Yahoo. That site's amazing photographic resource coupled with this tech would be incredible. Hopefully, they can do a deal.
