Assistir Assistir PobreTV. The 1981 performance Circle & Square by Takahiko Iimura, New York-based Japanese film and video pioneer, evolved from the artist's interest in exposing the apparatus of projection and the materiality of image and light, which began in the mid-60s. The work commences with the projection of a long loop of black 16mm film leader suspended from the ceiling. The artist punches a hole on the film's surface and as it loops through the projector's gate, a single white circle of light pierces the darkness. With each subsequent punch the film builds before the viewer’s eyes into a cascade of white circles before reaching its abrupt and revelatory conclusion.
