Highlights of the 13 works in the exhibition include Colored Vases, groupings of Han Dynasty pots covered in industrial paint. An expert in ancient Chinese ceramics, Ai?s continued desecration of individual vases can be seen as political comment on the organized destruction of cultural and historical values that took place during the Cultural Revolution, when everything old was replaced by the new. With Surveillance Camera (2010), the artist memorialises the clunky apparatus of CCTV surveillance by replicating it in marble, medium of monuments and gravestones. Themes of paranoia and voyeurism are evoked. Also on display were a number of key video works including Chang?an Boulevard (2004) which records Beijing?s central boulevard - the site of military processions and a location associated with the Tian?anmen Square protests of 1989 - at a sequence of measured distances along its forty-five kilometre length from east to west. In a film lasting 10 hours and 13 minutes, Ai offers a prosaic but mesmerizing portrait of the road. Pausing to gaze at construction cranes, office towers, power plants, and an endless stream of cars, bicycles, and pedestrians, the videos offer viewers a chance to stop and look at the city with a clarity that could never be achieved without the camera's mechanical indifference.
