I stayed awake after the news last night and watched the programme about Ai Wiewei the artist who designed the Birdsnest stadium for the Olympic Games in China and the current installation in the Turbine Hall at Tate Modern. I knew very little about Ai Wiewei before last night and still don't know a lot, but II am now very interested in him and in China. I am frustrated by regimes that stiffle or in most cases suppress any form of dessent. Can you imagine what it must be like to be a free thinker and have to live in a suppressed societey. I must sign off now as we have builders in and they will be here any second.
