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 1051

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

flow

Sixty thousand particles are advected through a vector field whose angle at every pixel is read from fractal noise. The image is the density of the paths they leave, log-compressed so the crowded areas do not clip.

graphite

Neutral black to white. The palette with no opinion.
