Patterns in the Poincaré Plane - Geometry Nodes: Part 1

I’ve made several serious efforts to really learn the depths of Blender’s Geometry Nodes. I was really into Sverchok for a while, but I’ve found Geometry Nodes harder. Maybe its the moving target as more nodes are added. Maybe without a scripting node I can’t cheat and just wrap code in a node front end. I have a bit more time lately and I think I’m starting to make progress.
