Make unit face mouse direction

[PrisonLove]

I sit possible to make it so that a hero unit will always face the direction the mouse is facing? For instance, as I move the mouse around, the hero will change it's facing to match the mouses position. Is it possible using the vanilla editor and if it is, how is it achieved? Both Jass and GUI solutions are welcome.
