The following description comes from the event organizer.

Bristlebots ring circles inside cast aluminum kitchen pan lids revealing a subtle play of overtones in delicate sustained resonance.

David Stanford and Dave Knott have been experimenting with bristlebots/hexbugs (little vibrating motor driven toy bugs) inside cast aluminum kitchen pan lids.  The result is a gentle, sustained ringing created by the perpetual circular motion of the hexbugs inside the lids, with periodic contrasting “pings” and all manner of subtle changes in overtones based on the action of each individual bug/lid combination as well as the interaction across multiple lids.  

An array of these automated overtone generators will be situated in a spiral formation throughout the room. The sunset through the Chapel’s west-facing stained glass windows will complement and integrate with the lighting below each of the lids.  Movement between and among the array will allow ample space for observing the environment for the duration of the sunset.
