<pre wrap="">I’m trying to find a nice way to do circular arc morphs; so far CurveMorph isn’t playing very nice for this and google is not finding anything that looks interesting.
Has anyone seen suitable code, or is anyone in possession of the Seekrit Knowledge of how to make CurveMorph do clean circular arcs?
