Computer scientists at the Centre de calcul, Université de Montréal discuss the earliest applications of computers to graphic design, animation and music, marking the era when computer graphics and animation were first being tested. The director of the centre, Claude Schnéegans, demonstrates the function of a graphic animation program activated by a magnetic pencil. Serge Poulard, a computer scientist, explains the educational applications used in collaboration with the professors from the University of Montréal. Gilles Gherbrante presents graphic works on paper and talks about their international diffusion. Electronic music and 2-D animation, along with the titles and credits, successfully support the work of these researchers.
