Dawn Chorus

Dawn Chorus consisted of an array of 35 cymbals, each of which has an attached DC motor and solar panel.  The motors were driven in real-time by sunlight and respond to changes in the weather, in particular, cloud cover.  Attached to the motors were lengths of flex, which beat out a rhythm on the cymbals as and when the motors are powered by solar energy.  In response to the varying feedback from the environment, the work autonomously produced different behaviours: sometimes a shimmering percussive noise whose intensity constantly changed, and periods of complete silence.
