A 4-by-4 grid of concentric rounded squares alternates between warm gold-yellow and cool avocado-green tones, each nested layer shifting slightly in hue to create subtle depth and visual rhythm. The palette evokes 1970s color sensibilities, while the mathematical precision and symmetrical repetition convey a meditative, almost hypnotic quality that speaks to that era's fascination with op-art geometry. 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.
