Chromophonie

On a black background, simple luminous figures change shape and follow trajectories. The film was made with the round tube of a 1950s television without scanning; the sinusoidal signals directly controlled the deflection coil, producing Lissajous figures. All the material was tube-powered. The colors were obtained by a disc with six colored sectors which rotated in front of the lens of the Bolex 16mm camera. This material is now in the museum reserves of the Cité des sciences et de l'Industrie in Paris.
