There was PhotoSynth but that creates 3d photoscapes out of several photographs (<a href="http://labs.live.com/photosynth/" rel="nofollow">http://labs.live.com/photosynth/</a>). Unfortunately but predictably, their demo runs only on Windows :)
site seems down right now (or at least really slow).<p>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)?
