Enjoy.

Cool! I guess this is similar to all the generators on the national grid
staying in phase. Although they're connected more strongly.

This doesn't happen naturally as far as I know. I had to use a
synchroscope to nearly match to the grid phase before attaching to the
grid.

Also, the behavior seen with the pendulum metrognomes would only work
with them aligned a certain way (with a feedback mechanism) and all
having the same period or simple ratios of periods.

I doubt that a room full of 'different' grandfather clocks with
different pendulum alignments and periods would exhibit this behavior.
