Somewhere, a few years ago, I saw a video in which a fairly large number of metronomes were mounted on a common base and exhibited some interesting injection locking behavior.
Personally I keep thinking of phase locking a G'father clock to a Rb standard. The trick will be to do so in a manner that requires no modification to the clock proper. And remembering to wind it at appropriate intervals- I'm too spoiled by watches and clocks that run for years at a time off a battery.
