My real frustration lies in the realm of music. I've been recording electronic music using strange software like WolframTones, which lets you 'evolve' pieces using cellular automata, or QuasiMusic which generates sounds mathematically from quasicrystals - patterns that almost repeat but never quite do. The fun part, and the hard part, is using these programs to create music that actually sounds good. I do a lot of sound editing using a free program called Audacity.
