OP art

Here I made a freehand illustration on Adobe illustrator, which is OP art. Before this, I made many OP art manually, but this time I wanted to try digitally. So, this is my first attempt at OP art digitally. What is OP art? Op art, short for optical art, is a style of visual art that uses optical illusions. Op art works are abstract, with many better-known pieces created in black and white. Typically, they give the viewer the impression of movement, hidden images, flashing and vibrating patterns, or of swelling or warping.
