A dense geometric grid of interlocking squares and circles creates a hypnotic optical illusion in deep red, soft pink, and black, its repeating pattern seeming to shift and vibrate across the composition. The pixel-like precision and retro color palette evoke 1970s computational aesthetics, drawing the eye into an almost kinetic visual rhythm that rewards sustained attention. 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.
