Venezuelan painter and kinetic artist Carlos Cruz-Diez broke new ground in color-optics during the Kinetic art movement of the 1960s. Deeply interested in color relationships, aesthetics, and perception, his influences include Georges Seurat's shimmering, pointillist compositions and Josef Albers’ illusionistic square paintings. His optical experiments focus on how color and line can create a sensation of movement as the viewer’s relative position to the artwork changes. In 1959, he shifted the emphasis of his work from paint to colored light.
