Interlocking yin yang symbols repeat across a bold black and white checkerboard ground, creating a mesmerizing optical illusion that shifts between figure and ground. The monochromatic palette and geometric precision give the composition a hypnotic, almost kinetic energy that rewards sustained looking. Printed on smooth white card stock and made to order, artwork on the front, blank inside, envelopes included in every set. A handwritten note that arrives as an independent artist's work.
