Street art is any art developed in public spaces and includes traditional graffiti(落書き), stencil graffiti, sticker art, video projections, street installations, and posters. Though it usually refers to art of an illicit nature, the term is used to distinguish contemporary public-space artwork from territorial graffiti, vandalism(芸術品等の破壊、汚染), and corporate art. Some street artists have even achieved mainstream recognition and commercial success.
