A wall of glossy ceramic tiles in mint teal and cream, with a block of raised glazed tiles at the center. Three square tiles with nested teal and ivory frames, glazed like thick ceramic buttons, hide the finder squares. The data modules appear as rounded, blobby teal and cream glaze shapes with small dots, spread across the central tiles. Strong contrast between the dark teal glaze and the pale ivory keeps the pattern clear, while the surrounding plain tiles and faint grout lines stay quiet around it.
