hello i got the idea from one of cg forums for 3dmax, the guy was using a cube that was moving on a curve to control the facial expression so here is the script : run it from the script editor and u'll have a UI now select your curve and hit the button on each control point on the curve u'll have a locator and u can use these locators to change the shape of the curve and there is a sphere on the curve , try to move the sphere !
