In 2008, Banksy invited 39 artists from around the world to paint a road tunnel in London over a weekend in May. The name of the festival is a play on the famous French film festival, the Cannes Film Festival. The tunnel has since been deemed a free-for-all, where it is legal for anyone to paint so long as they do so with respect.
