This is pretty trippy: David OReilly found that a large grid rotating at a certain speed will appear to group itself into smaller grids, rotating independently.
It appears the persistence of vision effect overrides our knowledge that this is a single grid and divides it up optically. This only seems to work on a uniform grid (I also had interesting results with a brick formation), but the effect is lost when using a checkered texture.

I think I saw a part of the intro to "Mindhunter" in the clip, as well as a scene from "The Joker" where the joker puts on his makeup. I wonder if it is just coincidence and they made their own video, or if they took clips from various sources.
If there is one branch of the military that should be good at finding employees, it should be PSYOPS. That they need a recruitment video has me worried.
