About this tool
A flow field is a noise function read as an angle: every point in the plane has a direction, and each particle simply takes a small step along the direction under it. The Perlin gradient noise here is implemented from scratch — a seeded permutation table, a quintic fade curve and bilinear interpolation — with several octaves summed for finer detail, so a given seed always reproduces the same artwork. Drawing is progressive on a canvas through requestAnimationFrame, and particle count and trail length are capped so the page stays responsive. The still PNG is produced in your browser; nothing is uploaded.
