»Black Square on Red Square«, 1992. A performance by Irwin in cooperation with Michael Benson, in which a square of black cloth, 22 meters to a side, was unfurled on Moscow’s Red Square, in homage to Kazimir Malevich and suprematism.

“Black Spot”, 2005 was a process in three stages. The first stage was to obtain a Satellite image of an area – in this instance Hyde Park, London. The second was to pinpoint a single pixel on that photograph and replace it with a black square of Polythene. The third was to take a second satellite photograph of the same area. By Phil Coy.
