“Call & Response” is a dynamic, computer choreographed public light installation designed for the corridor of trees lining the initial stretch of high street in Westgarth. Inspired by the short, silvery impulses produced by the Bell bird native to the Merri Creek region, the site specific installation sets up a series of light pulses in the tree tops, creating a call and response choreography through light and sound. Field recordings of Bell birds are played in each tree at interval, triggering light waves as a network of suspended LED tubes progressively light up in quick succession. Light trails leap across the canopies, connecting the next tree to bloom in response. The overall sensation is one of eerie wonder as the call and response of ghostly light animations play out in the tree tops above. In tandem with the techno-organic theme, the entire installation is powered by a number of solar panels on poles along the same tree-line, rendering the project fully powered by renewable energy.
