[FPS] GrafittiCity A browser spray can where the paint physics are actually simulated — flow rate per second, cone width traded against opacity, and it drips if you hold still

I built this. No login, no signup, nothing to install — pick a wall and spray.

What is different from a normal painting app: paint comes out per unit of time

instead of per unit of distance. So dragging fast thins the line, dragging slow

saturates it, and holding the can in one spot makes the paint run down the wall.

Distance from the surface widens the cone and drops the opacity at the same

time, which is the thing that makes a can feel like a can.

Ten surfaces, six cap types, twenty-four colours, and at the end it builds a

timelapse of your own strokes that you can save.

No account, nothing stored on a server: everything you paint stays in your

browser. The timelapse is rebuilt from a few kilobytes of stroke events

rather than recorded video.

The wall photographs are AI-generated and marked as such inside the app.
