Banksy is back!

Everyone's favorite mysterious guerilla spray painter is back in business. This week Banksy returned to Bethlehem.

For those unfamiliar Banksy is a semi-anonymous graffiti artist whose main focus is social commentary and criticism. His pieces are often satirical and they tend to infiltrate the institutions that he seeks to critique. For example, he planted pieces of art in the British Museum mocking the museum system and consumer culture.

Banksy first used the apartheid wall in the West Bank as a monstrous canvas in 2005. This week he is back for round two.
