Windy Sandbox
Windy Sandbox is a free interactive wind simulator that lets you paint storms, vortices, typhoons, and custom wind patterns directly onto a live world map and watch thousands of particles flow in response in real time. The product is built around a single, satisfying idea: you draw wind on a real map of the world, and the air moves the way you told it to, with thousands of animated particles tracing the flow as it happens. For anyone who enjoys interactive simulations that combine a real map with hands-on control, that paint-and-watch premise is the whole product.
The simulator runs on a live world map, so the wind patterns you paint sit on top of real geography rather than an abstract canvas, which gives the simulation a tangible, place-based quality. You pick a brush, drag on the map to paint wind, and the particle field updates live, flowing according to the patterns you have drawn. The interface reports the current frame rate and particle count — thousands of particles at a smooth frame rate — so the simulation feels responsive rather than sluggish, and the real-time feedback is what makes painting wind feel like shaping moving air rather than drawing a static arrow.
Windy Sandbox is free, created by an independent maker, and offered as a beta, with a support option and a Discord for the community around it. The toolset lets you switch map styles, choose brushes and tools, tune particles and colors, and work with a field section that includes a demo typhoon for an instant example. With save and load for the worlds you build and standard interactive controls — left-drag paints, right-drag erases, middle-drag pans, scroll resizes — Windy Sandbox is a complete, free wind simulator for anyone who wants to paint the wind and watch it move.
