Victor Vasarely is the father of Op Art and recognized as one of the 20th centuries most important artists.  His use of color, geometry and optical illusion in his art yielded fantastic results and influenced scores of younger artists.  As such, his paintings are in the permanent collections of museums around the globe and admired on a daily basis.  The example below shows a series of blue and red squares that come together to form a very ambiguous geometric pattern.
