The quality of the explanations, and progression of complexity, reminded me of an old video that explains how a car's differential (rear end) works:

Wow, this video was fantastic, thanks for sharing. I see how the progression reminded you of this, but the physical demo presents as more of a history-of-mechanisms lesson, which is fascinating.

I also appreciated the humor. They seem to have built a working mockup of a car with the driveshaft penetrating the passenger compartment, just to make the joke that it would be inconvenient to rest luggage on the spinning shaft.
