I don't know how many people know about it, but photosynth basically takes a lot of pictures, identifies if any of the pictures have any similairities, and meshes them together to create a virtual picture that you can fly through. It's pretty neat stuff, considering you can download pictures of the same thing, like a sculpture off the internet, mesh them together and then look at the whole thing, or zoom in to read text on the statue(if there are zoomed in photos in the collection). Anywho, to relate this to g3, I know that to make a photofield, it requires a 360 view, which consists of hundreds of photos. I think it would be cool to throw all of these photos into photosynth and make virtual fields there. Also, I was thinking that it might be possible to take 360 photos that have been uploaded there, and make a flying field out of them.
