This article goes over my head, but the title reminded me of my experiments writing simple 3D renderers. After several failed attempts to learn linear algebra, I had the shower thought that a 3D rotation is just three 2D ones, and that I already know how to do those. Within an hour or so I had a wireframe 3D renderer, perspective and all!

I encourage everyone to try it.
