Optical Art is a mathematically-theme form of Abstract art, which uses repetition of simple shapes and colors to create vibrating effects, foreground-background confusion, an exaggerated sense of depth, and other visual effects.
In the 1960's, the term "Op Art" was coined to describe the work of a growing group of abstract painters. This movement was led by Victor Vasarely and Bridget Riley. Blaze 1964
