throughout the mid-1980s. He associated with a variety of cultural figures, including longtime interlocutors Robert Anton Wilson and Allen Ginsberg; science fiction writers William Gibson and Norman Spinrad; and rock musicians David Byrne and John Frusciante. In addition, he appeared in Johnny Depp's and Gibby Haynes's 1994 film Stuff, which chronicled Frusciante's squalid living conditions at that time. Leary continued to take a wide array of drugs (ranging from serotonergic psychedelics to the nascent empathogen MDMA and alcohol and heroin) in private, but consciously eschewed proselytizing substances in media appearances amid the escalation of the war on drugs throughout the presidency of Ronald Reagan. Instead, he served as a prominent advocate for space colonization and life extension. He expounded on the eight-circuit model of consciousness in books such as Info-Psychology: A Re-Vision of Exo-Psychology. He invented the acronym "SMI²LE" as a succinct summary of his pre-transhumanist agenda: SM (Space Migration) + I² (intelligence increase) + LE (Life extension). Leary's space colonization plan evolved over the years. Initially, 5,000 of Earth's most virile and intelligent individuals would be launched on a vessel (Starseed 1) equipped with luxurious amenities. This idea was inspired by musician Paul Kantner's concept album Blows Against The Empire, which was derived from Robert A. Heinlein's Lazarus Long series. While incarcerated in Folsom State Prison during the winter of 1975–76, he became enamored by Princeton University physicist Gerard K. O'Neill's plans to construct giant Eden-like High Orbital Mini-Earths, as documented in the Robert Anton Wilson lecture H.O.M.E.s on LaGrange, using raw materials from the moon, orbital rock, and obsolete satellites. In the 1980s, Leary became fascinated by computers, the internet, and virtual reality. He proclaimed that "the PC is the LSD of the 1990s" and enjoined historically technophobic bohemians to "turn on, boot up, jack in." He became a promoter of virtual reality systems, and sometimes demonstrated a prototype of the Mattel Power Glove as part of his lectures (as in From Psychedelics to Cybernetics). He befriended a number of notable people in the field, such as Jaron Lanier and Brenda Laurel, a pioneer in virtual environments and human–computer interaction. During the evanescent heyday of the cyberdelic counterculture, he served as a consultant to Billy Idol in the production of the 1993 album Cyberpunk. In 1990, his daughter Susan, then 42, was arrested in Los Angeles for shooting her boyfriend in the head as he slept. She was
