A crowded night skyline of skyscrapers built from stained glass panes in red, orange, neon yellow, purple and blue. Dark leading lines separate each pane, and the tower blocks with their lit windows form the dark and light modules of the code, while the towers at the edges and the glass sky hide the finder squares. Strong contrast between glowing yellow panes and deep maroon and navy glass keeps the pattern legible across the dense detail. The sky above breaks into cracked blue and violet shards.
