Since the mid-1960s Bridget Riley has been celebrated for her distinctive, optically vibrant paintings. Her work as one of the main proponents of Op Art has earned her worldwide recognition with shows at the Museum of Modern Art in New York in 1965 and the Venice Biennale in 1968. (“Optical art is a method of painting concerning the interaction between illusion and picture plane, between understanding and seeing.” John Lancaster 1973).
She currently has an exhibition entitled Bridget Riley: Flashback at the Waterhall, Birmingham Museum and Art Gallery (BMAG). On until 23rd May the exhibition includes the iconic work 'Movement in Squares' (1961), which Riley credits as the beginning of her breakthrough into abstraction. On show, for the first time ever, are 30 works on paper mainly from the artist's own collection. http://www.bmag.org.uk/events?id=557
