There was PhotoSynth but that creates 3d photoscapes out of several photographs (http://labs.live.com/photosynth/). Unfortunately but predictably, their demo runs only on Windows :)
site seems down right now (or at least really slow).
Wasn't there a YC company doing this at some point? Is this one and the same (since view3.com seems to redirect to the same very slow and/or down stanford AI page)?
