Yes, let's crack on with it all on Wednesday. I'd talked about a separate installation, but I'm so busy with other things (just finished BR grant feedback form as one such!) that I'm inclined to work on as lower priority, maybe not in time for HB Arts Fest. Happy to reconsider if people think its feasible.
The idea was for people to interact via a paddling pool, with water movement/ level being picked up by 1 or more sensors, then connect that to arduino, which would transform into sound, fed into speaker laid on its back pointing upwards, & have some (preferably attractive) shallow tank of water on top, with little jets of water dancing whenever vibration comes through holes in speaker/ wooden template resting on speaker.
