Op artists like Edna Andrade were interested in the psychology of perception, using color juxtapositions and mostly geometric forms to create visually ambiguous works that suggest movement. "Hot Blocks" engages our awareness of the act of seeing with a dynamic illusion composed of 3D hexagons in black, white, and gray. "Hot Blocks," 1966–67, by Edna Andrade © Estate of Edna Andrade
