at Centre Georges Pompidou (Paris) and at 11th Biennale de Paris

1×7 Balayages

Arrangement of 7 monitors in vertical position, with modified scanning

centre Pompidou (Paris) from January 10th to 21st, 1979.

A single video tape is shown on 7 monitors whose scanning are modified to create symmetries in both axes (device height: 238 cm). When the image movements give an impression of concentration on the 4 monitors at the top left, the same image gives an impression of dispersion on the 4 monitors at the bottom right. The central monitor, common to both sets of four, is the only one to display the source image unmodified.

Device consisting of 8 programmed projectors

centre Pompidou (Paris) from January 10th to 21st, 1979.

Eight beams of light produced by 8 slide projectors (without slides) staggered in height, width and depth, are switched on and off according to a programmed sequence. There are no images, just rhythmic alternations of white light on the large screen of the theatre, which has been cleared of its seats. The spectator can position himself between the projectors and the screen and watch the intermittence of his own shadow move in relation to the axis of each of the projectors.

Faisceaux Black & Light

Film made up of holes projected vertically in a fog box

centre Pompidou (Paris) from January 10th to 21st, 1979.

An original loop from the film “Black and Light”, produced without a camera using a computer-controlled tape perforator, is presented in this installation as a vertical projection in a ‘fog box’ (height: 184 cm). It shows the movement of the twelve rays of light coming from holes made in an opaque 16mm film.

Installation for 6 stacked monitors

XIth Biennale de Paris from September 19th to November 2nd, 1980.

Six monitors, in a vertical position, one above the other, have their colour feeds modified to present 6 combinations: the RGB output of the video recorder feeds the RGB inputs of the monitors in permuted orders: RGB – RBG – BRG – BGR – GBR – GRB.
In the image, a white shape (therefore unaffected by chromatic permutations), whose movements are designed to ensure visual continuity between the bottom and top of the image so that the white shape appears to move from one monitor to the next.

Six superimposed monitors for Pierre Rovere's "6x3" installation at the Paris Biennale

Some other installations have been created.

In addition, some projects have been considered but never implemented, notably because of their gigantic scale, such as the Trias 511 installation, made up of 63 screens.
