I just got one, too, and had the very same thought. I've been working on my
clock for a few days now. I'm want to use a balance wheel instead of a
pendulum. I have a balance spring configured using a Lego rubber band and am
using one of the large six-spoke wheels (with tire) for the balance wheel.

short period of the balance wheel.
Using the wind-up motor and a balance wheel, I hope to end up with as
compact a clock as possible.
