Microsoft just announced a collaborative work with NASA to create a 3-D photo experience using a product under development called Photosynth: http://seattlepi.nwsource.com/business/326453_software06.html. Photosynth takes a collection of photographs and stitches them together for a rich, immersive environment. Check out the Space World site which is created in conjunction with NASA, Microsoft Live Labs and MSNBC: http://www.msnbc.msn.com/id/20098402/
There are a bunch of other Photosynch collections worth checking out including a Britain in Pictures: BBC Collection, Gyeongbokgung - a South Korean Temple, Piazza San Marco, Venice, Grassi Lakes in the Canadian Rockies, Gary Faigin Art Studio and Piazza San Pietro, Rome.
As a photographer, I love this stuff! The engaging experience that Photosynth brings to the site is almost as good as being there live - and in many cases it's even better. I've always preferred a good photograph to video because of how it freezes time and tells a story of how the photographer interpreted the moment. Photosynth brings all of these moments together and tells a story and the high resolution images let me explore details that I might otherwise have missed if I was there in person.
I could go on and on about all of the cool things you can discover on with Photosynth but it’s something you’ve just got to check out for yourself.
