Around the same time, psychedelic art made good use of spirals and kaleidoscopic patterns to suggest the effect of hallucinogenic drugs and altered consciousness. This and the influence of psychoanalysis is clear in films such as Vertigo (1958) in which director Alfred Hitchcock uses spirals to suggest the "downward spiral" into insanity of his main protagonist, Scottie; from the opening credits, a spiral whirling in a graphic eye hypnotises us as a man in silhouette tumbles into a well of psychosis.
