Every year, on November 5, marchers wearing Guy Fawkes masks take to the streets in cities around the world to voice their wide-ranging protest against the ‘system’. Guy Fawkes was a real person and the best known member of the Nov. 5, 1605 Gunpowder Plot to blow up the British House of Lords. After appearing in Internet forums, the mask became a well-known symbol for the online hacktivist group Anonymous, used in Project Chanology, the Occupy movement, and other anti-government and anti-establishment protests around the world.
