While the animated breakdown itself is phenomenal and certainly makes the video, one of the other key aspects is the progressive explanation of _why_ this mechanism is designed the way it is. You can watch the video without sound, and probably without the text as well, and see exactly how the "spikey ball" was designed, how the driver gears were created, how to get two types of movement from the drivers from linear inputs, and how those movements translate to moving the ball joint. It reminds me of the old Chevy videos, such as the one on differentials[1]. It was created in 1937, and through some live demonstrations and clever use of stop motion the film shows how to separate wheel movement, fix gear slippage, attach a drive shaft, then optimize for space. Different visual technology, but same type of presentation. There's similar videos for transmissions, suspensions, etc, all incredibly enlightening.
