LONDON.- As part of a series of new contemporary art projects for the Jubilee line, commissioned by Art on the Underground Irish artist, John Gerrard, is to present a large-scale installation of his work Oil Stick Work (Angelo Martinez / Richfield, Kansas) 2008 on a vast bespoke wall in the station. Using customised game-design software to craft stunningly accurate virtual worlds, Gerrard projects a complex digital moving image that eerily develops in real time and will continue to do so over the next 30 years. The viewer joins this hyper-real scene three years into its slowly unfolding story on a desolate Midwest prairie. At daybreak (PST), the tiny figure of Angelo Martinez, a Mexican-American builder, arrives at a solitary aluminium corn silo and carefully paints a perfect black one metre square on the exterior of the structure with an oil stick crayon.
