Pepper's Musical Wall Clock with Figurines

Those figurines do not turn around their axis, but they show a rocking motion during the full hour play while the bezel is turning. The mechanism is quite clever. First I thought, why does the bezel have to turn. Then I realized, that the turning bezel is nothing else then a huge wheel that will open the windows and rock the figurines. Clever mechanism.
