This video clip shows how the flocking algorithm operates in this installation. The viewpoint is that of looking at the installation from directly above, and each of the circles represents a channel of bird sound. When a listener enters the installation a camera tracks his/her movements. Certain movements can startle the "sonic birds" that are tweeting from inside the birdhouses. When this occurs, the "birds" begin flocking together, flying around the sonic space, and the listener standing in the middle of the installation will hear the sounds moving around the space. The "birds" eventually settle down and return to their original locations in the birdhouses.
