A cyan and yellow toy tractor with chunky black tires and pink hubs sits on a tiled classroom floor, ringed by building blocks and tiny toy animals. The finder squares are hidden in the tractor's wheels and the wooden chair backs, whose dark rims and square panels echo the module shapes. Scattered blocks and small toys break up the floor into light and dark patches that carry the data modules. Strong contrast between the black tires, bright floor tiles and sunlit desks keeps the pattern readable throughout the scene.
