The Ai Weiwei project at the Tate looks breathtaking. One Million porcelain sunflower seeds covering the great hall floor. The material has multiple meanings in the cultural narrative of Weiwei's work. I find myself alittle disappointed that they are not real sunflower seeds-I can work through the functional concern, three months of stepped on sunflower seeds-yuck. I can also follow the porcelain industry as key to China's economy and the gesture toward 100 million as a potent number in China. I can even work through the real/fake thing. But wouldn't have smelled great in there????
