hey guys, need some help here. I'm looking for a battery operated toy that has some sort of controlled "arm" movement. Sort of like a scissor movement or jumping jacks. It just has to move along one axis (up and down, front and back) but also have a controllable angle so that I hit a button I can raise the arm and another to lower it. I really hope I'm making sense. Anyone have any ideas? I need it for a project I'm working on. Once it's done I'll have pictures to show off the goodness.
