Black Shoals is an artificial ecosystem linked to the real time dynamics of the stock market. It was first shown at the Tate Gallery in 2001, and nominated for an Alternative Turner Prize in 2002. A more sophisticated Black Shoals was exhibited at the Nikolaj gallery in Copenhagen in the spring of 2004. Stars representing companies and creatures representing speculators are projected into a domed ceiling in a dark room, creating an artificial night sky which visualises the dynamics of the world stock markets.
