A tall lighthouse stands in black ink above crashing waves, with gulls spreading their wings around the tower and billowing clouds behind it. Square frames and a gallery of dark blocks hide the finder squares, while the tower's checkered stonework and the scalloped cloud and foam shapes carry the modules. Solid black fills against a plain white ground keep the pattern sharply defined. Fine stippling and thin hatch lines add shading to the swell without muddying the contrast.
