Scott Garner has created two sculptures that react to their environment and then produce sounds based on the input. In his own words:

For several years I’ve imagined a sculpture with a massive array of different sensors that processes the incoming data and then generates an abstract representation of it. In other words, a machine that simply observes the world with no use or function beyond that. This led to a series of explorations based on sensing and interpreting the world and finally to the two sculptures displayed here.
