Islands is an sound driven animation based on chaos theory. There are twelve soundtracks in this work: six were recorded at the Central, the busiest area in Hong Kong. The other six were recorded at Cheung Chau Island, one of the outlying islands in Hong Kong. The sounds as inputs in every second are drawn by using six attractor equations. The first track on the canvas represents a soundtrack recorded at the Central; the second at Cheung Chau Island. Two tracks share a same formula. Similarity and difference, and the beauty of the attractors are to be explored in this work.
