From 1994 to 2000, Morrison wrote "The Invisibles" for DC Comics' Vertigo imprint, which has been described by Morrison as a "hypersigil": "a dynamic miniature model of the magician's universe, a hologram, microcosm or 'voodoo doll' which can be manipulated in real time to produce changes in the macrocosmic environment of 'real' life." Both "The Invisibles" and the activities of Morrison himself were responsible for bringing chaos magic to a much wider audience in the late 1990s and early 2000s, with the writer outlining his views on chaos magic in the "Pop Magic!" chapter of "A Book of Lies" (2003) a Disinfo Convention talk, and the documentary "".
