Art review: Keith Tyson, South London Gallery, London

Keith Tyson's new exhibition is called Supercollider, the nickname of the CERN particle accelerator in Geneva. "Tyson's attempts to evoke the wonders of the universe include a sphere that changes colour (at least this is pretty), a big, tedious revolving machine with pieces of meteor stuck to it, a massive painting of the "infinite cellular blanket" that resembles a jokey version of the last days of 1960s art, and a 12-part drawing that can be arranged in any order called A Night in a Billion. Chance and the infinite unlikeliness of existence is his heavily stated theme."
