Around 1722 the English master clockmaker came up with the grasshopper escapement - a tiny internal device that releases a clock's gears to move forward at each swing of the pendulum.
Dr Taylor decided to show how the grasshopper escapement works, so he turned the clock inside out and, instead of making the escapement 35 mm across, it is 1.5 m across.
He calls the new version of the escapement a Chronophage or time-eater, a fearsome beast which drives the clock, literally eating away time.
With each slackening of the monster’s jaw, and release of its claws, another second is devoured. Each new hour is signalled by the rattle of a chain on an unseen coffin to remind passers-by of their mortality.
