Photosynth is an hexperimental photo mangler from Microsoft's Live Labs (who came up with Surface and the like). It takes a bunch of photos and stitches them into a 3D virtual cardstack kinda of thing - hard to describe, obvious once you see it, so
take a look at the site. It's free, you'll need a Windows Live login and there's a small download to install, after which it's a browser experience.
Here's my Croyde KAP photos loaded into a synth. It's done a remarkable job of tying together the pictures into something like a space, and I think it feels genuinely vertiginous.
