The group IOCOSE has been working since 2006. It organizes actions in order to subvert ideologies, practices and processes of identification and production of meanings. It uses pranks and hoaxes as tactical means, as joyful and sound tools. IOCOSE thinks about the streets, internet and word of mouth as a battlefield. Tactics such as mimesis and trickery are used to lead and delude the audience into a semantic pitfall.
