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 1002 --size hd

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

strata

A warped field folded through a sine into bands, then mixed back with the field it came from. Pure folding blows the highlights flat, so the underlying gradient keeps the majority weight.

ember

Charcoal warming through rust into pale sand.
