Music video for Daft Punk's Around the World: as RealVideo; Flash on YouTube [via robotwisdom]. Brilliant. Now, how can do me a machanima version, hook the dancer groups into different frequency ranges, and make the entire thing into an iTunes/WinAMP visualiser that I can use for any mp3? Come on! Visualisers should be way better than they are now.

I bet you could write the entire thing in Lisp and run it right in AutoCAD if you wanted, but a music visualiser would be cool too.
