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 1055

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

warp

Domain warping. A noise field is sampled through an offset taken from two more noise fields, so the texture drags itself sideways. The warp parameter is that offset, as a fraction of the short edge.

graphite

Neutral black to white. The palette with no opinion.
