I got a request this past week based upon a mixed transition diagram I'd posted to Facebook for instructions on how to do one of the transitions outlined in it: namely switching from root horizontal cateye to ET vertical cateye. Primarily I'm using gravity to help in this case, but there is a way to snap the poi head vertically to do it as a mixed transition with the hand soft--it's damned hard, though.

Had an interesting revelation over the weekend: thus far all the work I've done on the concept of transition theory (hard and soft transitions) has been restricted to 2D epi and hypertrochoid shapes. While playing with a mixed transition CAP pattern over the weekend, I suddenly realized I could repeat the pattern without altering its character by switching to the plane behind me. Technically, such a transition means going to an ET relative to wheel plane, but it behaves like an IT due to conservation of angular momentum.
