The most fun thing I ever did, not the most bizarre, was a dripping tap in my flat when I was a student in Brighton. I couldn't believe it was making all these musical noises, blip blop blip blop...
I made a piece from it, worked out the median notes then the timings and made an algorithmic composition from that, and that was fun.
