Thousands of brush strokes follow an invisible current of simplex noise, settling on rice paper the way ink settles when the brush is almost dry.

Each stroke samples a two-octave simplex noise field to choose its heading, thins as the bristles run dry, and skips fibres of the paper at random. Three passes — pale washes, mid tones, fine dark hairs — build the image. Turn on Flow to watch particles trace the same current in real time.
