This is an implementation of Brownian motion with Diffusion-limited Aggregation (DLA)
We have a lot of colloidal particles moving in brownian motion. In the very center of the canvas we have an ionized clump which is going to coagulate the moving particles when they come in contact and thus eventually form a larger ionized aggregate.

This implementation has been written entirely in C 😎. With the power of Webassembly it has been possible to render it in an html canvas.
Source code can be found here
Press SPACE or click on the canvas to toggle the render of moving particles.
Wait patiently and enjoy! Thank you.
