Artist Banksy created recently his biggest piece to date in central London. "Banksy pulled off an audacious stunt to produce what is believed to be his biggest work yet in central London.

The secretive graffiti artist managed to erect three storeys of scaffolding behind a security fence despite being watched by a CCTV camera. Then, during darkness and hidden behind a sheet of polythene, he painted this comment on 'Big Brother' society." Via Daily Mail.
