John Harrison’s Longcase Clock

Origins
Harrison was a British clockmaker and inventor of the ‘grasshopper escapement’; a mechanism that allows the gears in a clockwork to move at a precise interval.

Effects
The clock makes chirping noises that have a hypnotic effect. Opening the glass door of the clock unleashes a swarm of grasshoppers. The swarm can be ‘lured’ back in the clock by stopping the ‘grasshopper escapement’ mechanism.
