Taxonomy of corners

[Monday 17 November]

The first sketches for a taxonomy of corners (very rough; these were done in hotel rooms and airports during the Marrakech trip). I'm struggling with finding the right definitions: don't really think "1D," "2D," "3D," etc are correct. But over and above that, the experiment is giving me some interesting corner configurations that I haven't seen before.
