“Perception is the medium.” Bridget Riley took this as the title of a 1965 Art News essay, defending her Op art after MoMA’s The Responsive Eye show — her black-and-white canvases are less pictures than machines that make your own eye do the work. The seeing is the artwork: the painting completes itself only inside the viewer who looks.
