Another awesome work of art is shown now at the famous turbine hall at the Tate Modern in London. Ai Weiwei poured over 100 million sunflower seeds into the enormous space. Not real seeds but replicas in porcelain, each single one made by hand! Not only is the number gigantic and the effort mind-blowing, it's also a beautiful, simple and poetic piece of sculpture. I wish I could go and see it live.
