Yes the HandMorph is handled like any other Morph, it draws itself andafter that it draws all its submorphs. (And actually it does not use any caching, and it is still quite fast)
But yes, it needs a special drawOnAthens method.Do you plane to make a package for it ?I would like to integrate it in Bloc.What would like to integrate?
I will upload the changes in Athens-Morphic package tothe Athens repository.
