With the new knowledge gradually constructed lately, I returned to read this classic and it just downed on me that a strand-network (Penrose paper page 19 in the pdf linked above) can be given a structure of a collection of choroi, see the post
or better go to the paper “Computing with space“.
This is food for thought for me, I just felt the need to communicate this. It is not my intention to chase for theories of everything, better is to understand, as a mathematician, what is worthy to learn and import from this field into what interests me.
