hey ockham! Is this the same kind of problem you solved with your Jiggles script? I seem to recall the target MTs (or other parts) were influenced by the movement (including acceleration) of a "host" body part in absolute space. But I'm not sure if this is the kind of thing gwhicks is after. Anyway, tossing this out in case it rings any bells, strikes any chords, etc, etc. cheers... TG
