His slides provide a nice overview of this powerful suite of products, which include:

•  ATAudio, for handling audio files including music downloads and podcasting
• ATPhoto, which provides some powerful photo management features, including import and export from Flickr
• ATVideo, which provides tools for handling video files

There is also supposedly video, courtesy of Mr. Topf, but the link appears to not be working right now. :-(

A screencast would be nice -- like PrimaGIS, these are tools that are even more impressive to see than to read about.
