 The Source by Greyworld, in the new LSE building Greyworld are a collective of London based artists who are interested in public-activated art, sculpture and interactive installations. Although often varied in their approach, their work is typically subtle, environmentally reflective and requests special attention.
Although they have built up a rich history of acclaimed works since their formation in 1993, their most notorious piece, so far, is probably The Source and is a permanent feature of the new London Stock Exchange: A cube of 9x9x9 (729 in total) spherical balls are suspended on strings that stretch 32 metres up to the top of the main atrium of the newly designed building. These balls, controlled by a computer running Python scripts, can reposition themselves independently of each other, forming dynamic shapes and fluid-like motions that reflects the nature of the stock market itself. Each morning, upon the opening of the London Stock Exchange, the balls awake from their cube arrangement and begin to form patterns. Similarly, at the end of each day's trading, the balls fall back into their cube arrangement, and an animated arrow is shown using the blue LEDs inside the balls to show how the stock market performed on that particular day.
