This is merely a concept, but seems promising. What if you had a large umbrella shape with bells and other noise making things hanging from it.

The items might stay in place, hanging from above, but when the visitor turns a crank, an overhead device runs around the top of the umbrella, setting off all the noises as it goes around.

The visitor would have a circular sound experience as the jingling goes around and around.

This work, so far, lacks one of the elements we look for: a work that looks different after every time someone plays with it.

But rules are made to be broken and it’s still just an idea…
