In London, over the weekend 3–5 May 2008, Banksy hosted an exhibition called The Cans Festival. It was situated on Leake Street, a road tunnel formerly used by Eurostar underneath London Waterloo station. Graffiti artists with stencils were invited to join in and paint their own artwork, as long as it did not cover anyone else's. Banksy invited artists from around the world to exhibit their works.
Banksy's works have dealt with various political and social themes, including anti-war, anti-consumerism, anti-fascism, anti-imperialism, anti-authoritarianism, anarchism, nihilism, and existentialism. Additionally, the components of the human condition that his works commonly critique are greed, poverty, hypocrisy, boredom, despair, absurdity, and alienation. Although Banksy's works usually rely on visual imagery and iconography to put forth their message, Banksy has made several politically related comments in their various books. In summarising his list of "people who should be shot", he listed "Fascist thugs, religious fundamentalists, (and) people who write lists telling you who should be shot." While facetiously describing his political nature, Banksy declared that "Sometimes I feel so sick at the state of the world, I can't even finish my second apple pie."
