I also suggest taking a look at Bruno Militelli's Bismuth photographs
You can also find some 3d models of Bismuth on Sketchfab.
Modeling with Find Shortest Path
The Find Shortest Path node can be used not only for finding the shortest path between two points, but can be used to create complex, interesting path networks.
This file contains the example animation above, and shows a few different ways the node can be used: 2022_09_16_find_shortest_path_examples.hiplc
