Rain Painting

Open the app and a painting begins. Rain falls on white paper, colors bleed and bloom, and a pattern you've never seen before comes to life. Want a new one? Tap once. That's the whole app.

Rain Painting is an ambient art toy — part screensaver, part meditation, part tiny universe. Nothing here is drawn in advance. Every scene grows on its own, spreading across the canvas like watercolor on wet paper, shaped by the rain and by your finger if you touch it.

THE MATH BENEATH THE PAINT
The patterns aren't random, and even less AI. They come from reaction-diffusion — the math Alan Turing used in 1952 to explain a leopard's spots and a fish's stripes. Two invisible substances spread and react, and structure appears by itself. No two runs are ever the same.

Watch it before sleep, let it play in the background, or just sit with something beautiful for a few minutes. Rain Painting asks nothing of you.
