Wilson's agent to adapt the trilogy. Illuminatus! #1 was issued in July 1987, then reissued in substantially revised form later that year by Rip Off Press (who had published the original 4th edition of the Principia Discordia in 1970). A second issue followed in 1990, and a third in March 1991, after which the venture stalled (although several ashcans of the as yet unpublished Fourth Trip were distributed at comic book conventions in the Detroit and Chicago areas between 1991 and 2006). Influence The infamous 1980s computer hacker Karl Koch was heavily influenced by The Illuminatus! Trilogy. Besides adopting the pseudonym "Hagbard" from the character Hagbard Celine, he also named his computer "FUCKUP", after a computer designed and built by that character. He was addicted to cocaine and became extremely paranoid, convinced he was fighting the Illuminati like his literary namesake. In 1987 he wrote a rambling seven-page "hacking manifesto of sorts, complete with his theories on Hagbard Celine and the Illuminati". The 1998 German motion picture 23 told a dramatized version of his story; Robert Anton Wilson appeared as himself. A card game, Illuminati, inspired by the trilogy, was created by Steve Jackson Games. Using the Illuminatus! books as "spiritual guides but not as actual source material", it incorporated competing conspiracies of the Bavarian Illuminati and Discordians and others, though no characters or groups specific to the novels. A trading card game (Illuminati: New World Order) and role-playing game supplement (GURPS Illuminati) followed. The instruction booklets' bibliographies praise the novel and Wilson particularly, calling Illuminatus! in part "required reading for any conspiracy buff". Robert Shea provided a four-paragraph introduction to the rulebook for the Illuminati Expansion Set 1 (1983), in which he wrote, "Maybe the Illuminati are behind this game. They must be—they are, by definition, behind everything." Despite this initial involvement, Wilson later criticized some of these products for exploiting the Illuminatus! name without paying royalties (taking advantage of what he viewed as a legal loophole). The Illuminatus! Trilogy is steeped with references to the 1960s popular music scene (at one point a list of 200 fictional bands performing at the Walpurgisnacht rock festival is reeled off (including a handful of actual bands of the 60s), and there are numerous references to the famous rock and roll song, "Rock Around the Clock"), and has influenced many bands and musicians.
