Benham Fechner Colour Illusion

Also sometimes called subjective colour illusion. This illusion generally consists of a spinning disk that is half black and half painted with concentric patterns (black and white). When spun at the right frequency range, the illusion of coloured rings appears. Various explanations exist and none conclusive.
