Vector fields 🏹

Divergence & curl 🌀

What are you looking at?

This is a dynamic particle and vector field simulation where points interact with sources, sinks, and swirling currents. Every particle moves according to the invisible forces around it, tracing the flow of this small, colorful universe.
