Street art is any art developed in public spaces, though the term usually refers to unsanctioned art, as opposed to government sponsored initiatives. The term can include traditional graffiti artwork, sticker art, wheatpasting and street poster art, guerrilla art, and street installations. Sebastian Buck from Los Angeles, California, USA, created Unurth, a blog where he collects photos of street art from all over the world.
