A shallow layer of water is captured inside a sealed acrylic dish mounted on top of a steel column. The steel base plate that supports the column sits on a bed of hundreds of springs that allow the plate to flex as people walk on it. The vibrations from people walking are transferred up the pole and revealed by waves in the surface of the water. The system is sensitive enough to reveal the heartbeat of a viewer standing on the base plate. The artwork was part of an exhibition entitled: “Data + Art”, that was curated by Dan Goods. Completed in 2009.
