Bill Mack (Born 1944) is an American contemporary artist best known for his innovative use of lenticular imaging and bas-relief techniques that blur the line between painting and sculpture. Rising to prominence in the late 20th century, Mack gained recognition for works that create shifting visual effects, often featuring figures, faces, and iconic imagery that change as the viewer’s perspective moves. His art frequently explores themes of beauty, perception, and illusion, combining classical subject matter with modern technology. Mack’s work has been widely exhibited and collected internationally, earning him a reputation as a pioneer in three-dimensional visual art.
