These articles are attempts to write up some of the theory and implementation of my "geom2018" project, which is a graphics & game engine based around tesselations of the plane by regular polygons (largely squares & triangles).
The name "geom2018" is just the name of the Git repo in which I began the project's most successful incarnation, back in 2018. However, I've been thinking about this project, and starting & abandoning small implementations of it, for several years before that.
The primary outcome of the project has been the Spider Game.
