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. Built from double-wall stainless steel and made to order, holding 20 ounces with a snap-on lid, a standard-cup-holder fit, and wraparound artwork. Your commute carrying original art instead of another branded tumbler.
