This is a very simple demonstration of a recursive tree in 9 lines of code (not counting the setup). Good as a demonstration tool for recursion. I intend to tag this for Customizer once Customizer supports recursion. 26/4/15 This model now supports customizer! Play with it and see what happens.As soon as I heard that OpenSCAD could handle recursion I whipped this up. I plan to do more elaborate things soon but I thought I would put out a very simple demonstration of recursion to help people get the idea without extra baggage. As a bonus it produces a printable tree!
