This is a neat idea, from a fantastic perspective - I feel like many of the art projects I saw were visually oriented and my auditory senses were bored by the end of the week. Too much bing-bing-bing / whoop whoop whoop whoop coming from one direction at a time. I'd enjoy a more ludicrous source of non-standard cacophony. This is also dandy because, (well, in the vision I made in my head) you can stand in the middle of it and have sounds all around you. It seems kinda spiritual and happy hippy-like too. There are many ways which this could go, and a good lead would be needed to keep people like me from converting it into too many ideas at once.
Also, it seems a little non-professional, a little non-commercial, more messy... and somehow, in music, that sounds like more fun.
Did you have any idea so far as how the noises would start? This is off the top of my head, but what if it were multiple strings of noisemakers that were linked... i.e., if someone poked the bells at point "a," chimes would be heard in a string away from them, up to a horn at point "e," then rattles along "e" to "p" would diffuse the completing orchestra? A person at "b" could start a whole different string of sounds. Or perhaps it's not even fueled by people at all, perhaps it would be better if a sail was designed to catch the wind and run along a track, smacking all the bells?
On a completely different note, my inner 3 year old / gorilla just wants to smash things that make noise until I am content.
Lastly, I've considered making a moop monster - something semi-exotic and mostly transparent that would accumulate moop that I have re purposed and safetied (e.g., encapsulated feathers in silicone) and securely attached to it in a monstrous fashion. Part of this fantasy was the concept that it would become a worse "bad trip" daily as the Burn progressed, partially this would give me the obscure pleasure of asking people with feathers to donate them to my art project.... I wanted to say that your idea (I hope, in my imagination) has a much more calming and polite effect.
Hmm, that's my thoughts at a glance. I sent you an email too.
