After his arrival in Paris at the end of 1958, Le Parc began to paint pictures with simple geometrical forms (squares, circles, rectangles) because he considered them more neutral than irregular forms and therefore closer to his aim of removing all trace of the artist's touch and of subjective composition. He made paintings first in black and white, then in colour, with the forms and their relationships in accordance with a predetermined programme. Experiments with a systematic scale of colours in different permutations led him to imagine these variations succeeding one another in time, and hence to experiment from late 1959 with various types of mechanism for achieving this full range of variations. This marked the beginning of his tendency to move away from the creation of a static, unique, finalised work and to explore effects of movement, chance and variability.

His first experiments along these lines culminated early in 1960 in light boxes, with movable elements like shutters. These were followed soon afterwards by numerous other experiments, including some with movable parts adapted from those originally intended for the inside of the boxes. One such series consisted of a number of perspex or metal squares or rectangles of uniform size suspended vertically on thin nylon threads in front of a background of a contrasting colour (black on white, for instance, or red on green), in such a way that they could move continually in the air currents. In another series small transparent or mirrored squares were substituted for the opaque ones and hung at angles of 45 degrees against a white background, thereby introducing an optical dematerialisation of the basic elements, with reflections of the surroundings picked up by the moving squares and a play of moving light reflected onto the white background. As extensions of this idea he then set up artificial light sources in various places in a darkened room, experimented with bending the background so as to accelerate or slow down the reflections, and even made a work in 1962 with the hanging elements suspended in the middle of a darkened white room and scattering moving reflections from four beams of light across the walls, ceiling and floor. The result of these and other such experiments was the creation of a kind of art-spectacle, a visual situation which was continually different but nevertheless also basically the same.

The works with suspended squares are usually known as 'Continual Mobile' and those with changing light effects as 'Continual Light', but the Tate's piece, which combines the two themes, is entitled 'Continual Mobile, Continual Light'. It has a diagram and written instructions on the back explaining that it should ideally be shown in a darkened space and lit by raking lights from both sides. The artist confirms that it is a unique work, though there are several variants on the same theme.

(This note is based on the artist's published statements, above all on the texts in the catalogue of his retrospective exhibition at the Städtische Kunsthalle, Düsseldorf, in 1972).
