An art movement is a tendency or style in art with a specific common philosophy or goal, followed by a group of artists during a specific period of time, (usually a few months, years or decades) or, at least, with the heyday of the movement defined within a number of years. Art movements were especially important in modern art, when each consecutive movement was considered as a new movement.

PHSYCHEDELIC
graphics or visual displays related to or inspired by psychedelic experiences and hallucinations known to follow the ingestion of psychedelic drugs such as LSD, psilocybin, and DMT. 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".
