The British street artist Banksy just painted nine provocative murals on the wall that separates the West Bank from Israel. The sardonic quote in the title is Banksy's reflection on his work there. He goes into a little more detail on his site. The Guardian and BBC both covered it, and there is at least a little disagreement over the meaning and relevance of politically-motivated street art here and here.While we're on the subject of Banksy, here's my previous favorite project of his. As the BBC sub-head describes it, "Fake prehistoric rock art of a caveman with a shopping trolley has been hung on the walls of the British Museum."
