There is a TED presentation, where we see really good looking geometries, which are generated using space folding.
I get the general idea, that we start from a basic geometry like a cube, and then apply linear transformations and conditional foldings (reflecting a point on a plane). I tried it, but my results were not really good looking.
I am looking for the algorithm, to generate geometries like that. But by guessing I can not progress further. Unfortunately I was not able to find articles, explaining it.
This is an example from the video:
