Synopsis

This is a film composed entirely of frames of solid black and solid white, which Kubelka strings together in lengths as long as 24 frames and as short as a single frame. When he alternates between single black and white frames, a rapid flicker of motion-pictures projection is seen; during the longer sections of darkness one waits in nervous anticipation for the flicker to return, without knowing precisely what form it will take.
