Your eyes are lying to you and Bridget Riley is responsible — the optical shimmer of black and white patterns that seem to breathe, pulse, and warp the surface of reality. Moiré interference, impossible vibrations between figure and ground, and the thrilling vertigo of staring at something flat that insists on moving. Inspired by Riley's Fall, Victor Vasarely's planetary grids, and the 1965 MoMA show 'The Responsive Eye' that made critics nauseous and audiences delighted. The pattern is static. Your perception isn't.
