Procedural 2d fluid simulation in geo nodes

This simulation runs entirely in blender geo nodes. You can customize the initial speed and color the particles using either a built-in noise textures or an image. Time scaling is achievable through the fps slider.

For optimal results, i suggest rendering in Cycles, as Eevee currently does not support rendering particles as spheres without manual instancing.

Geo nodes setup:

Shader for the particles:

You can use the built-in noise textures or an image file for point coloring.
