Concentric arc patterns in varying line weights stack and flow across the composition, creating a rhythmic visual movement reminiscent of water ripples or geological stratification. The grayscale palette shifts subtly between light and dark tones, producing a hypnotic optical effect 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.
