The Guardian has an article and photos related to my earlier mention of Banksy in the West Bank. A choice quote for those unfamiliar with the wall:

Although the paintings themselves are not overtly political, his feelings about the wall are apparent from his statement: "The Israeli government is building a wall surrounding the occupied Palestinian territories. It stands three times the height of the Berlin Wall and will eventually run for over 700km - the distance from London to Zurich. The wall is illegal under international law and essentially turns Palestine into the world's largest open prison."
