Eric,

Precision pendulum clocks, when mounted near each other,
have been known to eventually get into phase lock. So one
idea is to add a GPS 1PPS driven bass speaker or solenoid
or some sort of thumping contraption. Perhaps eventually the
pendulum clock would lock to the vibrations on the the wall.
