Watch Feedback Stroboscopy (1975) Official Trailer

1975, the golden age of analog manipulation! In the midst of my fascination with the video feedback effect, the equivalent of the Larsen effect for sound, I generated these soaring images by directly connecting the camera to a video monitor while passing through Marcel Dupouy's Movicolor Synthesizer and following the repetitive rhythm of a composition by Nana de Vasconcelos (with, as a bonus, the blessing of Pierre Barouh and Saravah)! -- Dominique Belloir
