I've just spent a great hour watching a video called "Hello Live Labs" which featured Live Labs Group Program Manager Karim Farouki explaining what Live Labs is, the rationale for it, and some of the technologies they are up to. I was disappointed not to learn much that I didn't know already but this was still the deepest dive I have seen yet into Photosynth and, in particular, Seadragon. If you ever seen the Seadragon Bleak House demo and wanted to know how it works then this is the video for you.

There was mention of a new product that they are working on called Seahorse but unfortunately we didn't get to learn what it actually is. Karim also intimated that pretty soon we'll be able to build Photosynth collections of our own.
