Hope you’re doing fine, too.
If I had to guess, I’d say that the woolly paths (or edge-bundling) simulation from your first reference picture, was probably done with Processing and the geometry from the bottom picture reeks of mesh modelling. My guess would be that it was hand-modelled in Maya (or any other polymodelling app) and that the woolly paths simulation was just a pretext to go nuts with the poly-modelling.
As you can see, your reference project probably has very few to do with Rhino and Grasshopper.
However, there are a couple of edge-bundling Grasshopper definitions out there, I believe. Simply search this and the old forum.
For the rest, Rhino and Grasshopper are really not the way to go. Modelling this in Rhino would be way too tedious and take you forever, and setting this up in Grasshopper would be a nightmare (even “impossible”).
