According to Microsoft (labs.live.com/photosynth), "the Photosynth Technology Preview is a taste of the newest – and, we hope, most exciting – way to view photos on a computer. Our software takes a large collection of photos of a place or an object, analyzes them for similarities, and then displays the photos in a reconstructed three-dimensional space, showing you how each one relates to the next. In our collections, you can access gigabytes of photos in seconds, view a scene from nearly any angle, find similar photos with a single click, and zoom in to make the smallest detail as big as your monitor.
