Yvaral is Victor Vasarely's son, but he deserves to be considered an artist in his own right. Jean-Pierre Yvaral is one of the founders in 1960 of the GRAV movement with François Morellet, Horacio Garcia Rossi, Julio le Parc and Joël Stein. This movement advocated an accessible art for the spectator. The latter could, in some cases, touch and manipulate certain works. The GRAV was publicly launched in 1963, in a manifesto "Assez de mystifications" on the occasion of the third Biennale of Paris.
A quotation in this manifesto allows us to better understand the principles of this movement: "We want to interest the spectator, to get him out of inhibitions, to relax him. We want to make him participate. We want to place him in a situation that he triggers and transforms. We want him to move towards interaction with other spectators. We want to develop in the spectator a strong capacity for perception and action."
Yvaral's art is mostly composed from algorithms and is strongly inspired by the art practiced by his father. Yvaral is the inventor of the term "art numérique" in 1975. By the term "numérique", we must understand: an art based on mathematical ideas. In 1985, he developed a technique with the use of computer tools in order to structure his works in a perfect way. He is also an adept of experimental art and passionate about optical illusions.
Some of Yvaral's works are kept at the Museum of Modern Art in New York or at the Tate in London. At the same time, the artist has done important works of architecture and design. He also created the logos for Renault and the 1996 Atlanta Olympic Games.
