I first heard about Microsoft’s Photosynth technology about a year ago. It uses computers to stitch together photos to create interactive panoramas. The more photos used, the more interactive the panorama is.
The biggest use for something like this is an event where you have lots of people taking photos on their own that you can feed into the system.
Lets see, what happened today that might be cool to play around with this tech?
Oh yeah, the election in front of the U.S. Capitol.
CNN is way ahead and put one up, its pretty cool and you should check it out:
