Click the green flag to generate a root, a river or a lightning strike. Click the settings button to show sliders you can play around with.
I got the idea to make this when making the project "Super Slo-Mo Lightning": https://scratch.mit.edu/projects/557226736/ This pattern occurs in many other things as well. For example, if you change to red colors, it looks like arteries. Can you come up with more examples?
