Flow Field

An ambient particle toy: thousands of invisible particles follow a randomly generated mathematical flow field and paint silk-like trails across the canvas. Stir them with your finger, burst a swirl with a tap, switch between five palettes and save any frame as a PNG.

Warming up the flow…

Drag to stir the flow — tap to burst a swirl.

What is this

1
A living screensaver for your browser tab
Over a thousand particles drift along an invisible mathematical flow field, painting silk-like trails as they go. Nothing to win, nothing to lose — it just keeps moving.
2
Stir it with your finger or mouse
Drag across the canvas and the flow bends around your motion. A quick tap bursts a fresh swirl of particles at that spot.
3
Five moods, one field
Switch between Aurora, Ember, Ink, Bloom and Reef palettes, roll a completely new random field with one click, or clear the canvas for a fresh start.
4
Keep the pretty frame
Save whatever the canvas is showing right now as a PNG wallpaper. It all runs locally — no account, no uploads, no tracking.
