A still from the movie Saw II - This is a still showing one of Jigsaw's victims. He has a variation of the Iron Maiden, a helmet with nails on the inside. If he fails to unlock it within the time specified, the helmet will snap shut, driving the nails into his head, killing him. The catch is this: The key is in his eye socket. To live, he will have to pry the key out of his own eye socket. A typical Jigsaw trap.
