Yeah, I learned that there is a whole process to rent astronauts in space by the hour for experiments or whatever. There was a part in that talk about sending the camera up that I don't remember, but I wish I did.

A separate part of the same talk was about a different screensaver. The flyovers through the cities and how they used math to figure out the exact time and place for the lens flares so they would be real. They also talked about removing all the billboards/ads from the buildings.

It was all just great stuff.
