Here is a very nicely made wood automaton featuring an alien performing the famous cups and ball routine. It's a time-honored theme in the history of automata, which have a long association with magical illusions. This one does have a unique twist in that the performer -- what looks to be an alien in sunglasses -- has three arms. When the handle is turned, the alien shows the ball under one of three cups. He lowers the cups covering the ball and gives them a magical shake back and forth. When the cups are raised again, the ball has mysteriously moved from one cup to another.
