Bridget Riley is one of England's most well-known artists known for her op art paintings that use optical illusions to create the sensation of movement. Her early work from the 1960s was done primarily in black and white and featured wavy lines that appeared to ripple or change as the viewer moved. Riley's paintings are intended to produce disorienting effects like flashing, vibration, or warping for those viewing them. The term "Riley sensation" was coined to describe the dizzy feeling one gets from looking at her op art style.
