Psycheelic art is art inspired by the psychedelic experience induced by drugs such as LSD, Mescaline, and Psilocybin. The word "psychedelic" (coined by British psychologist Humphrey Osmond) means "mind manifesting". By that definition all artistic efforts to depict the inner world of the psyche may be considered "psychedelic". However, in common parlance "Psychedelic Art" refers above all to the art movement of the 1960s counterculture. Psychedelic visual arts were a counterpart to psychedelic rock music. Concert posters, album covers, lightshows, murals, comic books, underground newspapers and more reflected not only the kaleidoscopically swirling patterns of LSD hallucinations, but also revolutionary political, social and spiritual sentiments inspired by insights derived from these psychedelic states of consciousness.
