Seth Godin talks about Dafen in a bunch of his books. There is an entire section of the town that just makes monkey paintings. My favorite anecdote is about one of his monkey paintings that inexplicably has what looks like a teardrop on it. He said he was confused about this for a while, but then realized what must have happened -- some rain got on one of the paintings, and from then on everyone just kept copying the smudge. (Part of a larger riff about how not everyone who makes paintings or whatever is an artist.)
