Name of the pendulum thing with five balls suspended on strings?

    Hey guys

    I know you're probably going to laugh at me for this question, but what is the name of the pendulum thing with five balls suspended on strings? You know, the thing that every boss has on his desk in every movie? I have been trying to figure it out for a while now.
