One corner is much like any other; a right-angle, that's all. It's all rather simple. I've heard the ancient Egyptians only knew about one right-angle, and that's good enough for me. I only know about one right-angle, too. Anything more than that would be too complex. That different stuff should occupy that right-angle is a parallel concern of my studies. These cats, for instance, are operating on a purely geometric level. Purely geometric.
