(Louise) (1931-) English painter. She was a pioneer of Op art. In the early 1960s she invented her characteristic style, arranging hard-edged black and white dots or lines in regular patterns to create disturbing effects of scintillating light and movement. Fission 1963 (Museum of Modern Art, New York) is an example. She introduced color in the late 1960s and experimented with silk-screen prints on Plexiglas. + prikaži više
