Toilet cleaner brand Domestos is celebrating World Toilet Day with a piece of public sculpture that lets Londoners take a virtual crap in public. It created The Public Toilet, a five meter tall sculpture of a man answering the call of nature, on the riverbank next to London mayor Boris Johnson's HQ. People can visit The Public Toilet's website to upload a photo or video of own their face to the sculpture, and share with friends. Agency Lean Mean Fighting Machine is responsible for the stunt, which aims to draw attention to the 1.1 billion people in the world who cannot go to a private toilet.
