In my current build I decided to try something that I have always wanted to do, that is to design a brick built tree that works the way that real trees work, following a fractal design where each limb spreads following the same formula and connects like real branches do.
The branches in this tree are very robust, the only weak point being where the large branches connect to the base of the trunk (a single stud connection). The plan is to use these trees in several of my new Neo Fabuland builds, and you can check out the instructions to build them yourself below:

Well there you go, there is my new spreading tree technique, let me know if it is useful to you!
