This was constructed from an obscure piece of aeronautical hardware I procured at the Pratt and Whitney Surplus Store in Hartford CT. I snaked stainless steel wire from it to act as resonators. Then at key points I installed piezo transducers. At the center the stainless steel wires stab into a banana and a pear. The whole works sits atop a speaker that the transducers constantly feed back.

Standing waves appear on the floor surrounding the piece and viewers' position and footsteps alter the resulting drone.
