Optical Illusion Art or Opt Art is a genre based on mathematics that presents optical illusions. To produce these types of illusions, the patterns of moiré are created with the help of the repetition of form and color. Many of the opt art images are painted in black and white color only and the viewer who tries to understand these images will only see hidden images, three-dimensional forms, movement, foreground or background confusion and other stimulation.
