Psychedelic art is any art or visual displays inspired by psychedelic experiences and hallucinations known to follow the ingestion of psychoactive drugs such as LSD and psilocybin. The word "psychedelic" (coined by British psychologist Humphry Osmond) means " mind manifesting". By that definition, all artistic efforts to depict the inner world of the psyche may be considered "psychedelic". In common parlance "psychedelic art " refers above all to the art movement of the late 1960s counterculture. Psychedelic visual arts were a counterpart to psychedelic rock music. Concert posters, album covers, liquid light shows, liquid light art, murals, comic books, underground newspapers and more reflected not only the kaleidoscopically swirling colour patterns of LSD hallucinations, but also revolutionary political, social and spiritual sentiments inspired by insights derived from these psychedelic states of consciousness.
