Recursive Tree

Played around with OpenSCAD. Was inspired by openCscad from Thingiverse user smcameron: http://smcameron.github.io/opencscad/ Tried to do the same thing with recursion within OpenSCAD. For a more natural looking tree, please look at this thing: http://www.thingiverse.com/thing:128686 UPDATE: As Thingiverse User Ablapo pointed out, recursion is not (yet?) supported by the Customizer. So i changed the script to a 'pseudo recursive procedure': I just chained the needed the modules together! Not unbeautiful, but it works this way. I will post another truly recursive script when the Customizer can handle it. UPDATE II: I did some optimisation in the code, it runs now twice as fast... and with more colors!
