Photosynth is a new MS Live Labs project that lets you take a huge collection of photos of a single place and organize them into a 3D landscape. Let’s say you just returned from your summer vacation and you want to see what’s around the corner of a monument you photographed. Photosynth is the solution. You can pan, scroll, and zoom. It’s as if you were actually there. You can see or download a video of Photosynth in action here.
