This is an oldie but goodie, Microsoft Research showing off their scene stitching and management software called Photosynth. The program lets you navigate and view linked and related images without having to pre-tag photos. It also lets you fly thru a scene of photos to view them from any angle. It even recognizes key objects in a photo and automatically applies hyperlinks to them. So far its sounds cool, like a super charged iPhoto on crack but the really cool stuff is its 3D stitching capabilities.

Photosynth allows you to recreate three dimensional experiences you can navigate thru by stitching together 2D photos of that scene. For example, you want to relive your recent trip to the Eiffel Tower? Assuming you took enough photos, Photosynth can recreate that seen for you to view and share.

Best part is it’s free. You’ll need a decent graphics card with XP SP2 or Vista installed. Happy photosynthing!
