A desert plain of saguaro and barrel cacti, red rock buttes and blue-grey boulders spreads beneath a pale full moon and an orange sunset sky. Rock pillars, cactus clusters and dark green shrub patches carry the dark modules, while the rippled pink sand and glowing sky supply the light ones. Large boulders and tall buttes take the place of the finder squares. Strong contrast between shadowed green and rock shapes and the bright sand keeps the pattern clear across the scene.
