After looking more into cellular automata, I have realized that it is very restrictive and my project won’t work with it. So, I have tried to use fractals instead.
This was the result:
At first, I wanted one fractal that expands depending on where the mouse is, but somehow that did not work and it came out like this. I like it because it gives the “nature” vibes and it makes me think of multiple things that we find in nature.
