Room in London

If you glimpse some horrible excrescence sprouting from the roof of the Institute of Contemporary Arts (ICA) in The Mall, London, don't panic. It's merely a three-part "sculpture" Room in London (2009/10) by Austrian piffle-peddler Franz West. It was previously installed in Rome's Piazza di Pietra. They should have left it there. It will infest the ICA roof until 29 January 2012.
