It was in 1963, at the 3rd Paris Biennale, that François Morellet exhibited his first work using neon lights as part of the GRAV Labyrinth. That year, he wrote: “It is a hard, cold material that appeals to me and allows me to make use of time and rhythm”.

For him, the light source as a visual art material gave rise to new experiences: random sequences, overlapping rhythms, variations in light… to which was added the active participation of the viewer, which lay at the heart of the artist’s work during this period.
