A round ceramic plate with a gold rim, glazed in indigo and purple speckles, holds a cluster of pink lilac blossoms and pale green leaves. Three square glazed tiles with blue and white concentric rings disguise the finder squares. The data modules are carried by black spotted patches in the glaze, which sit against a lighter lavender and cream ground behind the flowers. That strong dark-on-light contrast keeps the pattern readable even where the blossoms overlap it.
