I am wanting this ring to appear as a twisted chain, hopefully with a variable number of 180 turns it makes as an integer input to the Geometry Nodes group. I want the chain to be twisted as a whole. I.e. if you were to cut the loop and suspend the chain so it hung from an end, it would untwist, like a twisted rope swing.
This is the ring I have with the geometry notes. This is currently incorrect:
These are the nodes I have:
How best to make instances twist about a curve in Geometry Nodes?
Edit: Here is a demo of what I'd like to achieve. Apologies that the rings are intersecting each other. This is not desired: They are meant to realistically link together.
Note that I would like to be able to adjust the starting angle, to achieve a rolling effect, like this:
