Collatz Conjecture

After I watched Collatz Conjecture in Color - Numberphile, I was inspired to try visualizing the Collatz Conjecture myself. I was also keen to finally try out some Houdini!

I first tried to generate the strands using a VEX Detail Wrangle node, but unfortunately the VEX compiler crashed when I wanted to make use of arrays in structs. I instead used the Python node inside the Geometry SOP to generate the tree. Below are the results!

Thanks to Numberphile for the inspiration and @pixelkram for showing me some of the Mantra renderer features.
