Congratulations, Ai Weiwei. You win for most art elves! Lining a grand hall with 100,000,000 hand-painted porcelain “seeds” for Ai Weiwei’s Unilever Series at London’s Tate Museum took 1,600 Chinese artisans.  When asked if the visitors can take home some sunflower souvenirs, Ai Weiwei gave the vague I-would-but-maybe-you-shouldn’t response. Tate says “NO!” But since the artist has been repeatedly harassed and beaten nearly to death by authorities, he probably won’t mind a little rule breaking.
