Eigenradio [via muxway] analyses radio stations, pulls out the most statistically significant frequencies, and plays them back at you. Wicked. "The best of the New Music, distilled and de-correlated". (Listen to it for a bit, and every so often you get a burst of recognisable drum loop, or at a longer frequency and hear something more classical. Occassional patterns, solidity, strata, in the noise. So many things like this.)
