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 1070

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.

kelp

Deep green water, silt, and light near the surface.
