My initial EE Senior project proposal (back in the early 90's) was a biofeedback controlled music generator. The idea was to use a Markov chain (not that I knew that term, but I'd heard of the concept) to produce tone sequences, then use biofeedback to alter the probabilities to encourage relaxation. With my luck, it probably would have devolved into a metronome, but I was young and naive. I ended up failing out of college (I was young and stupid, too) and when I returned 5 years later I ended up changing my senior project to a leg controller for a hexapod robot.
