A dense grid of interlocking green and white squares shifts and undulates across the composition, creating an optical illusion of depth and movement where flat geometry appears to ripple and breathe. The rhythmic pattern builds a hypnotic, almost tactile surface that draws the eye inward, evoking the kinetic energy of 1960s op art through precise, mathematical precision. 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.
