I saw this video today of this new technology for pictures and it blew my mind.

I can't believe how much he could zoom in to pictures and have them all as one tile like that. Pretty incredible.
I also recommend trying out the software he showed in the 2nd half. Here's a link: http://labs.live.com/photosynth/
It's pretty incredible.
