The Radioactive Orchestra has an assortment of over 3,000 radioactive isotopes which you can use to create music. Strange as that sounds, it is a first class way to get an instinctive understanding of radiation decay behaviors and patterns, allowing you to directly perceive the activity. And, with a little mixing of isotopes and adjusting your BPM rate and root frequency you can actually end up with an interesting music bed from which to build your own compositions. They also have some wave filter functions; it defaults to a sine wave, but try a square wave or sawtooth for some interesting acoustic variations. Thanks to the folks at New Scientist for the heads up on this one.
