Purescript L-System
Creating L-Systems with Purescript, using purescript-drawing for drawing and purescript-flare for controls.
This is just a toy project. I implemented three example instances from the Wikipedia article: the fractal tree, the Sierpinski triangle, and the fractal plant. I think the plant is the coolest, so you can try it out here: https://hrantzsch.github.io/purescript-l-system/index.html.
