A carved wooden relief of layered, flowing grain in warm mahogany brown and pale cream, set inside a curved frame. Thick dark ribbons of wood twist across the middle and read as the code's dark modules, while the cream lattice behind them supplies the light areas. The three finder squares are hidden within looping wood forms and rounded cutouts of the white lattice. Strong tonal contrast between the dark brown curves and the pale carved ground keeps the pattern distinct, and fine contour lines add depth without cluttering it.
