Orange sand dunes roll across a desert dotted with green cacti, blue agave and a distant city of domed adobe towers. Three large concentric rings in terracotta and cream, each with a dark hollow center, disguise the finder squares. The data modules are carried by the dark orange shadows cast on the sand, plus the small round cacti and dark pits that fill the dune floor. Strong contrast between the deep shadow shapes and the pale sunlit sand keeps the pattern readable, while the green plants add detail without breaking it up.
