Mouse on/off effect

i am after replicating this effect:

the circles around the 3d box move when moused over and return on mouse off, but the direction they move in is dependant upon the direction the mouse hits it.

as a relatively basic action scripter, can anyone point me to an example .fla of this method or help me in any other way?

thanks!:sigh:
