The first film shot entirely with polarised light. The filming was done by projecting pieces of glass directly onto the camera (the constantly changing images and colours become visible through a glass screen that divides the beam of light directed at the camera). The images are accompanied by music composed expressly by Luciano Berio. Fragmented, reduced to the infinitesimal, in space and time, the shapes and sounds continue to produce images: minimal, instantaneous events that the rhythm transforms into narrative and that populate the film like a kaleidoscope.
