Tim Noble and Sue Webster are London-based artists who collaborate to create large scale installations. Sculptures of haphazard piles of broken wood are transformed into detailed figurative images when light is projected onto them. Their latest show, titled Nihilistic Optimistic, includes six sculptures which create self-portraits of the artists. The exhibition is on until 24th November at Blain Southern at Hanover Square (nearest tube is Oxford Circus). You can read more about their work on thisiscolassal website.
