Haven't had so much fun with e-music ever! Courtesy of Mike Calore's Monkey Bytes blog on wired.com, I downloaded Sound-Of-Traffic, a nifty Java code, created by one other than John Weir of smokinggun.com fame. His Java Synthesizer converts the IP/TCP message headers of the data packets traversing the net into music notes that you can individually manipulate. Cool!
This, enhanced with Garageband and combined with the Eyephedrine (by GioFX) visualizer on Apple's iTunes client can produce some deeply resonating, addictive audiovisual experiences. (For me, at least....) If you're into mashups, send me a comment and I'll point you to the FTP directory where you can download the sound and/or the video file, under the Creative Commons Attribution license.
