Photosynth is LIVE!

I talked about this cool service a little while ago - it's really cool.  From the videos, it's really exciting.  But even more exciting is that it's now live!  Photosynth is a great way to do internet tourism, as well as ... well, it's hard to explain exactly, but one picture can put you back in that place.  Great for memories, great to see other pictures that are out there about the same area.
