闪烁（1966）

The Flicker is a 1966 American experimental film by Tony Conrad. The film consists of only 5 different frames: a warning frame, two title frames, a black frame, and a white frame. It changes the rate at which it switches between black and white frames to produce stroboscopic effects. Conrad spent several months designing the film before shooting it in a matter of days. He produced and distributed The Flicker with the help of Jonas Mekas. The film is now recognized as a key work of structural filmmaking.
