It's 4am and I'm calling it for the jam!
This project turned out way more challenging than expected, and in the end I had to resort to ad-hoc solutions to get growth that looks somewhat tree like.

I realise that the proper system will have to involve some skeletal physics simulation of sorts. The paths branches take greatly depends on surrounding factors, such as access to sunlight, and proximity to other branches.

I definitely want to return to this project at some point. The foundation is in place but more research will be required.
