Really great. Can you give some details about the implementation?

they are generative paths (list of points that form a line) and i use this path to render a path orientated cylinder. My class then has a list of children nodes that can be filled or not by a random given number, and those children have children and so on. its a recursive function that goes to a random depth to create the bush-like piece you see growing up. the rest is just a sphere and a few cylinders with no children attached.
