My characters aren't "twitching" but they do like to use their arms to talk. Hellouin even looks like (WARNING-do not read any further if you are squeamish) he's going to pick his nose sometimes

Of course, he' just touching his moustache.
So far, there have been enough characters with different movements that it hasn't bothered me but if there's any looooong scenes coming up where I have to watch the same person over and over...well, I might need your duct tape too!
