Keith Tyson’s work is concerned with the systems by which we represent and classify our understanding of reality. His Studio Wall Drawings form a significant part of his artistic output and reflect his day-to-day thoughts through a diagrammatical style, using text, numbers and graphic devices such as arrows. In SLG 3.2 (Index) we see a list of the works to be included in his Turner Prize-winning SLG exhibition Supercollider, 2002, along with sketches and scale drawings of the works. The drawing captures Tyson’s thought process in planning an exhibition of his work, of which the drawing itself becomes a part.
