It's 2058 and Louise Bourgeois's Maman spider sculpture is back in the Tate Modern Turbine Hall - and it's grown 25 per cent bigger.
Dominique Gonzalez-Foerster is the latest artist to take on the challenge of filling the Turbine Hall for six months.
TH.2058 is her response to the space, looking 50 years into the future as Londoners take shelter in the former Bankside Power Station from the neverending rain outside.
The eastern end of the Turbine Hall is filled with 200 bunk beds scattered with books. The titles have been carefully chosen to act as a bibliography for the overall installation.
Replicas of a number of well-known sculptures – including Henry Moore's Sheep Piece and Louise Bourgeois's Maman – have been created at Pinewood Studios and installed in the Turbine Hall. The twist is that the incessant rain has caused the artworks to grow in size by a quarter.
Gonzalez-Foerster insists the work is not pessimistic but explores a "culture of quotation in the context of catastrophe".
• TH.2058 is in the Turbine Hall at Tate Modern until 13 April 2009.
