I watched a video preview for this either on Channel9 (http://channel9.msdn.com) or YouTube, I can’t remember now. If I find the link I’ll post it. When you watch the video, you just assume it’s one of those technologies you won’t see for a while, or will never see. Something crazy tucked away in a lab somewhere… well, there’s now a sample online that you can play with, and I must say it’s pretty amazing. I’ll reserve my final judgement for the release that lets me upload my own photos. Until then, check out the Photosynth preview: http://labs.live.com/photosynth.
