Here's another quick web experiment, this time exploring the use of particle systems to generate art.
You can watch it generate a random forest live here: https://wybiral.github.io/code-art/projects/trees/
Or if you're one of the cool kids you can clone the Git repo or browse the code here: https://github.com/wybiral/code-art
Each tree starts as a single particle representing the trunk and moves upward with a random chance of bending or splitting as it goes. The branches are rendered using a technique similar to the spray can from MS Paint to create a charcoal look. Random pixels are faded out as it runs to create a grainy fog effect.
