I like Photosynth. I like it so much I can’t wait to Photosynth my house or get my holiday pictures in that system, all tagged with additional data so you could really experience the trip like we did sort of.
The Live Labs team just released a new Photosynth project they did with NASA. You can now see some exclusive footage of the space shuttle while on the launch pad or coming back from a flight atop at 474 for instance. All of this can be viewed here.
There’s also a video about the technology and how these Photosynth collections are made that is pretty cool.
