Procedural generation of geometric forms.
Start with a base polyhedron and create complex and unique forms by layering transformations on top.
Unity source code is available here: https://github.com/IxxyXR/Polyhydra
If anyone feels inspired to contribute I'd be overjoyed to accept pull requests, bug reports, presets, suggestions or even hate mail.

Partly based on https://github.com/kaonasi (which in turn is based on the work of Zvi Har’El: http://www.math.technion.ac.il/S/rl/kaleido/ ).
Conway operator code by Will Pearson @mcneel from https://github.com/pearswj/buckminster
(Zvi Har'El has sadly passed away. I've tried to contact all potential copyright holders to see if it's OK to make use of their work as a basis for this but I've had no luck in getting a response. Please get in touch if you're an interested party. I'd love to put a proper open source licence on this)
My original inspiration was 3DS Max's Hedra plugin which kept me entertained for quite a while nearly 2 decades ago. :-)
