Ai Weiwei: Sunflower Seeds

Art is a tool to set up new questions. An interview with Ai Weiwei about the work behind is installation "Sunflower Seeds", on display at Tate Modern from 12 October 2010 to 2 May 2011. Sunflower Seeds is made up of millions of small works, each apparently identical, but acutally unique. However realistic they may seem, the life-sized sunflower seed husks are in fact intricately hand-crafted in porcelain, by the inhabitants of a small village close to Bejing.
