Op Art

Movement in Squares, by Bridget Riley 1961

Op art, also known as optical art, is a style of visual art that uses optical illusions.
 Op art works are abstract, with many better known pieces in black and white. Typically, they give the viewer the impression of movement, hidden images, flashing and vibrating patterns, or of swelling or warping.

Op art is a perceptual experience related to how vision functions. It is a dynamic visual art that stems from a discordant figure-ground relationship that puts the two planes—foreground and background—in a tense and contradictory juxtaposition. Artists create op art in two primary ways. The first, best known method, is to create effects through pattern and line. Often these paintings are black-and-white. (Wikipedia)


The video bellow is a good example of what we are going to work on.

We are going to try the colored version of this optical illusion.
