1. Before the computer… there was OP ART!

2. OP Art = a form of art characterized by the use of geometric shapes and brilliant colors to create optical illusions (such as motion).

3. Even though your mind wants to believe that some of the squares are closer and some farther away; the real difference is due to the variation of size. Vocabulary: Optical Illusion = visual images that differ from objective reality

4. Non-objective Art = art that does not represent an object, person or place. Abstract Art is (more accurately) the simplification of a subject; whereas, non- objective art is created without a subject in mind.

5. Victor Vasarely is considered the father of OP Art. He was born 1908 in Hungary. He later settled in Paris in 1930’s and became a French citizen 1959. Victor created hypnotic works that look as if they were created on a computer beginning in The 1940s.

6.  Vasarely’s contemporary works featured animated surfaces of geometric forms and interacting colors.  In the 1960s he used even brighter colors to suggest movement through optical illusion.

26. Bridget Louise Riley was born 24 April 1931 in London; she is a famous OP Artist who created many black and white images in the 1960’s that created a sense of motion.
