Plongeon ou le Grand Disque is the first film to be made using the 2-metre diameter Large Stroboscopic Disk (LSD), designed by Dominique Willoughby and produced by Achay Doan, which provides a new form of stroboscopic animated painting, a contemporary adaptation of the 19th century stroboscopic disks and phenakistiscopes invented in 1833 by Joseph Plateau and Simon Stampfer. From the line to an animated being, serpentine, fish, human, swimming, flying, plunging into a bottomless space simultaneously expanding and shrinking, from birth to stellar disintegration, indefinitely, swimming endlessly in loops and spirals.
