ELI5; Not sure if it‘s jus me, but I‘ve been wondering why when looking at a picture where a person has a shirt with a lot of stripes and scrolling past that pictures, it creates this weird jittery glitchy effect. For example: https://www.instagram.com/p/B7WA60ApvzI/?igshid=xl3ysn4fwxh4

I am not an expert but I believe this is an example of [Moiré](https://en.wikipedia.org/wiki/Moir%C3%A9_pattern). This is the same effect that can make striped things through screen doors look strange or perhaps more appropriately its the reason that striped or checkered patterns always look strange in TV.

Essentially think of your computer screen as a very fine mesh, as you scroll past it blocks out different parts of the stripes. Our eyes and brains actually are not great at detail but the one thing they understand is movement and we see the unevenly changing stripes and interpret them as moving.

I’m a bit lazy to explain it.
Here you go.
