context_page_description: Greyworld are a collective of London-based artists who create public-activated art, sculpture and interactive installations. Although often varied in their materials, their work is typically subtle and environmentally reflective, often allowing participants the opportunity to play through the work. The following descriptions are of a few selected artworks.
context_section_description: Although they have built up a rich history of acclaimed works since their formation in 1993, their most celebrated piece so far is probably The Source – a permanent installation for the new London Stock Exchange: A cube of 9×9×9 (729 in total) spherical balls are suspended on cables that run the full 32 metres height of the main atrium of the newly designed building. These spheres, controlled by a computer running Python scripts, can move themselves independently of each other, forming dynamic shapes, characters and fluid-like motions that reflects the nature of the stock market itself. The sculpture opens the market each morning at 8am, with the spheres breaking free from their default cube arrangement to form elegant patterns and shapes.
  Throughout the day the sculpture responds to reputable news feed and displays snapshots of the current headlines, written in full height of the atrium. At the end of each day's trading the spheres return to their cubed arrangement, resting on the sculpture's base, and blue lights inside each sphere are illuminated to show the stock market's closing price with an arrow to indicate how the market performed on that particular day. Her Majesty Queen Elizabeth II unveiled the sculpture on 27 July 2004 and the opening was broadcast to a global audience. The installation is broadcast every morning on television to an estimated global audience of 80 million people. It was nominated for an Interactive BAFTA award in 2005.
