The mechanical sculpture holds an hour glass horizontally and it waits for someone to push the top/bottom button ...instead of turning the hour glass left or right, the robot tilts its head at you, a quick nod. Those who hold the buttons down, will only watch the robot continuously tilt its head at the audience, rocking back an forth as though it studies the button pusher.

The work stands five and half feet tall. This machine uses only relays to activate the head response. It was constructed before I started learning programming PIC microcontrollers.
