Well worth seeing.

Went to see Ai Weiwei's exhibition at the Royal Academy. An amazing, very moving show exposing some of China's corrupt ways. In 2011 he was arrested and detained for 81 days for criticising the regime. He was watched for 24 hours a day by 2 guards who were forbidden to talk to him but who watched every movement. The walls and everything in the windowless cell were encased in plastic. After his release he made models of this experience and this is one of them. Well worth seeing.
