Animatronic Eye Mechanism

If I had one of these Animatronic Eye Mechanisms I could put it to good use this Halloween.

“In order to make it possible for puppet eyes to be animated a puppet eye mechanism (commonly called an “eye mech”) must be constructed. Some eye mechanisms are manually controlled by the puppeteer’s hand inside a puppet’s head or externally via a cable control, string or lever. Moving puppet eyes can also be remotely operated using radio control.”
