Plug-in Media, the Brighton-based crazed Flash wizards led by our own Seb Lee-Delisle, has recently finished an impressive 3D baseball visualization for Major League Baseball.
They used our Effects branch (now merged with Great White), including a custom perspective line for the pitches. Certainly an impressive piece of technology.
You can get more information about how the application works here, and check an example here by selecting the Gameday tab.
A great example that shows how 3D can be used to visualize sports data and stats.
