A spired castle rises at the top center of a dense tangle of swirling white ribbons, spirals and concentric rings on a dark navy ground. Round wheel-like circles with fine radial hatching take the place of the finder squares, while the looping ribbons and stippled fills carry the dark and light modules. Strict black and white contrast keeps the pattern readable, and the fine hatching is spread evenly across the whole field. The castle towers and arched windows stay recognizable inside the flow of lines.
