Julio Le Parc (Mendoza - Argentina, 1928), participates in the student protests of Fine Arts where they demand the updating of teaching methods in art, closer to the avant-garde and abstractionism. At the age of thirty he receives a scholarship sponsored by the French government, where he forges his career, there he begins to draw his experimental and mathematical works, grids that repair and play with dimension and movement.
During these years, in the company of his friend Francisco Sobrino, he created his first light boxes and mobile constructions. Le Parc created installations in the 60's with distortions that are typical of the conjunction of mirrors, reflections and light in the interior of building spaces with the aim of altering perception to the limit of questioning reality and the factor of creating 'other worlds'. The inclusion of motors in the work was gradual, the objective is the presence, the participatory dimension is the body.
He belongs to the GRAV (Groupe de Recherche D'Art Visuel. Visual Arts Research Group. 1960-1968), with the participation of Argentine and French artists.
