When we first heard that Chinese conceptual artist Ai Weiwei had filled the Tate Modern’s enormous Turbine Hall with millions of sunflower seeds, we were intrigued. And then we discovered that each seed was made of porcelain, and had been individually sculpted by one of hundreds of artisans working on the project in the Chinese city of Jingdezhen. The end result of this “mass-production”: 150 tons worth of faux seeds. Truly mind boggling. Photo credit: Tate Photography © Ai Weiwei [via Boing Boing]
