Sunken stone ruins with ancient columns, a mossy arch and worn steps sit inside a round frame, with algae, drifting bubbles and bright tropical fish around them. Square stone pedestals with hollow openings and the carved block high on the wall take the place of the finder squares. Dark gaps between pillars, plants and floating bubbles form the modules against pale aqua water. Strong light-to-dark contrast between the glowing teal center and the shadowed rim keeps the pattern legible.
