Recently showing at the Tate Modern, Yayoi Kusama’s interactive Obliteration Room began as an entirely white space, furnished as a monochrome living room, which people were then invited to ‘obliterate’ with multi-coloured stickers. After a few weeks the room was transformed from a blank canvas into an explosion of colour, with thousands of spots stuck over every available surface. It was conceived as a project for children, and was first staged at the Queensland Art Gallery in 2002.  Check out more videos from the Tate at Channel.Tate.org.uk.
