Simplex noise
American computer scientist who invented gradient noise in 1983 and simplex noise in 2001, the smooth randomness behind most generative textures and flow fields.
Long, evenly seeded currents gather into folds of silk. A smooth noise displacement bends each strand while leaving room for the drawing to breathe.
Ken Perlin's simplex noise, 2001

Evenly spaced strands sample a smooth simplex-noise displacement. A tapered envelope brings their ends back into alignment, while curvature and depth shape the folds. Motion moves through the noise field along a closed orbit.
