These boxes are NOT MOVING.

Wild. Aliasing is real. We can be easily tricked.

these vocals are unreal

Craziest optical illusion I've ever seen.

Amazing, what’s the trick?

Amazing!

how

Yeah, but something moves in the background. The boxes' lines are actually drawn by transparent cuts on a blue surface. There is a moving black and white striped background. So we feel it.

If you put some work into it I think you can have them move

That's similar to time, an illusion.

@mathladyhazel But the shapes change

Cover the arrows and they still appear to be moving.
