Claude Fable 5.2 draws a huge ASCII lighthouse-and-moon scene purely via chain-of-thought

When @repligate saw a massive ASCII/Unicode artwork titled "The Lantern and the Drowned Moon," he asked whether it was generated programmatically.
Author @liminalbardo clarified it came from Claude Fable 5.2 in a basic "backrooms" setting with no code execution — the model drafted the entire composition in its chain-of-thought first, planning the gradient-shaded moon, the striped lighthouse, the sea reflection, and the boat row by row before writing out the final piece. The screenshot shows the full thinking trace, with the model meticulously shading crater patches and lantern beams like a human artist.
It's a striking demo of long-horizon spatial planning and character-level layout from a frontier model — hundreds of precise ASCII lines produced purely through reasoning.
