Every value above is derived from the seed alone. Run this and you get this image back, bit for bit:

python gen/render.py --seed 1031

The renderer is on the code page, about 300 lines of NumPy and Pillow.

cells

Worley cells: for every pixel, the distance to the nearest scattered point and to the second nearest. Their difference draws the cell walls, which is then mixed with a warped field for texture.

graphite

Neutral black to white. The palette with no opinion.
