I know this topic has been done to death, but in trying to come up with a way to classify toroids, I came to realize we've barely scratched the surface of them. Here I use the approach of imagining the axes around which we can move the plane of a toroid as being similar to the major axes inside an octahedron and choosing specific axes that are parallel with the arm, hand path, or neither. The result is a vastly more diverse world of movement than I had imagined and the really exciting thing is that each of these types of movements overlaps with the other two in ways to create opportunities for the kind of bridges we see with Noel's transition theory.
