THE ENIGMA OF OP ART: In the 1960s, the British artist Bridget Riley began to develop a distinctive style characterised by repetitive geometric patterns. With her explorations of the dynamic nature of optical phenomena, Riley became one of the most prominent exponents of what came to be known as Op Art.
