Thanks to Chad for passing along this video, and thanks for the vote of coolness in thinking that I had already seen it. In fact, I had not and had no idea what was going on with it until I investigated further.
Radiohead has not only (again) embraced technology for its own expression but has taken steps to allow fans to use play with the technology themselves. There is a full google-hosted section of a site with info about the video, the technology and the code and an app that allow you to manipulate the data (the video) and create. There is also a making of the video (if we can call it that) that should be checked out. This follows their previous experiment with the song Nude, where they released snippets of the song to the world and asked for remixes.
Pitchfork says it all better and with much longer wind than me
