Though totally different in scope, it reminds me of a device I saw at a street fair in Glasgow. This was a bank of drainpipes, arranged in a circle. One end of each pipe had a pressure washer head with a flat nozzle played across it, and the other end was stopped at just the right length to play a note. The pressure washer triggers were arranged as a keyboard, and there was a (laminated against water damage) music book on the console. You could play simple (if very loud) tunes.
I’ve never seen such a device since then.
