1951-1955: Kinetic images, black-white photographies: From his Gordes works he developed his kinematic images, superimposed acrylic glass panes create dynamic, moving impressions depending on the viewpoint. In the black-white period he combined the frames into a single pane by transposing photographies in two colours. Tribute to Malevitch, a ceramic wall picture of 100 m² adorns the University of Caracas, Venezuela which he co-designed in 1954 with the architect Carlos Raúl Villanueva, is a major work of this period. Kinetic art flourished and works by Vasarely, Calder, Duchamp, Man Ray, Soto, Tinguely were exhibited at the Denise René gallery under the title Le Mouvement (the motion). Vasarely published his Yellow Manifest. Building on the research of constructivist and Bauhaus pioneers, he postulated that visual kinetics (plastique cinétique) relied on the perception of the viewer who is considered the sole creator, playing with optical illusions.
