Having worked as a Fitter and Turner at VSEL (now BAE Systems) before becoming an artist, it is understandable that Keith Tyson often brings a scientific or technological aspect to his work.
His most famous work is probably 2001's 'The Thinker (after Rodin)', a black hexagonal structure (a bit like the totem-thing at the start of 2001: A Space Odyssey) filled with computers that emit a perpetual humming noise. In 2002 Tyson was nominated for the Turner Prize and achieved notoriety when Culture Minister Kim Howells left a note deriding the work as "cold mechanical, conceptual bullshit".
Tyson's work is indeed cold, mechanical and conceptual, but it's hard to see why that might be in any way a bad thing.
