I like that you are able to "design" a rule that constructs a 2-D grid. It brings success to an endeavor that appears difficult to do, at least within the confines of the Wolfram topological system. I also like your other post, "How Do Particles Talk?” – a communication framework, https://community.wolfram.com/groups/-/m/t/3080342. In your other post you explain how information can be stored in the nodes of a grid.
Perhaps between these two posts, you or others may be able design a 3-D grid or lattice? If these information storage and design principles work, additional features can be programmed in to approach something closer to a real physics model.
