Modeling the World
I forgot to mention the launch of Modeling the World, a collection of videos and the start of a community from Microsoft Technical Computing.
The lobby is the most interesting bit, and features a gravity simulation developed by Joel Pryde. I was in charge of the video player, which features Smooth Streaming video, a transcript, and extras timed to specific cuepoints in the video. You may remember much of this functionality from Project Tuva.
