During his period of involvement with the Groupe de Recherche d'Art Visuel (1960-8) Yvaral worked exclusively in black and white, and was concerned mainly with the systematic analysis of moiré effects, produced by the use of vinyl cords.
He wrote on 30 September 1965: 'This work "Relief cinétique - accélération optique" forms part of my research into moiré effects, optical acceleration, and the visual instability obtained by the shift in position of the spectator. "Optical acceleration" means that the movement perceived in the work appears to be more rapid than the movement of the spectator. It should also be noted in this work that its elaboration is based on the anonymity and uniformity of the forms themselves, in such a manner that the eye is not drawn to any single element or part of the work but, on the contrary, takes in the surface in its entirety.
'The technique used (transparent vinyl cord in front of a network of black and white) was first used in my work in 1961.'
