Yes, and segueing into clocks, and related to the balance and motion theme,
there were clocks made with the clock face on the front of a pendulum bob.
The clock movement was concealed inside the bob, and as it ran, it caused
the pendulum to swing. The motion of the pendulum actually regulated the
clock, even though it was not mechanically tied to the escapement.
