Mathematical Sculpture

Impressive. These are all more advanced than something like the staple cube (https://www.tiktok.com/@meimeitiktok4/video/7116863895171583...) I was expecting

Some of these remind me of Ángel Duarte who made this beautiful piece of art (French page but image is the interesting bit: https://fr.m.wikipedia.org/wiki/Ouverture_au_monde).

These are quite clever. I'd love to have my own Borromean Box.

That said, I've no clue how to start. It looks simple at first, but seems more complex the more I think about it. Some construction details, videos, or other hints would be much appreciated.

Please give instructions for the assembly, as you gave already cutting specs for the Poker Face thing. Would appreciate :)
