Greyworld did a talk at Dare a while ago. They are amazing. This is from their newsletter:
On the 20th November 2007, greyworld’s latest work, entitled Monument to the Unknown Artist, will be unveiled. Commissioned by Land Securities for the property company’s Bankside 123 development, the public-activated sculpture will be unveiled on a busy site behind Tate Modern. At first glance, Monument to the Unknown Artist appears to be a simple bronze statue, dressed in a neck scarf and loose fitting suit. However, the super-sized monument will seek inspiration from passers-by, inviting them to strike poses which he will copy, continually changing his form in a light-hearted and mischievous way. The unique sculpture will offer an alternative and accessible creative experience for the public allowing them to create a dialogue with the work of art.
