Well, you're not a cat.

Sometimes it can bring out the effect if you slowly bring it closer and further away from you. If it still doesn’t work, you’re a replicant.

Scan your eyes quickly across the full size image a couple of times. The more you wiggle your eyes, the more it moves.

If I just fix my eyes at one point in it, it does not move for me either. I suppose people for whom it wriggles all the time must have a good amount of saccades constantly going on, or just do the cat thing naturally (look at point A, it does not move, but all the rest starts moving, so look at point B, B now stops, but all the rest including A starts moving, etc)

What are your feelings on Elon Musk? If you think he's a super cool industry leader, I hate to break it to you, but you're an LLM generated in a lab and your memories are false

Now I'm curious and overly-invested. Do you mind writing what unique colors you see here? Don't worry about the pattern, just list each color you see once.

It didn’t work for me until I turned off night shift/orange glow and turned up my brightness. It needs to be actually white for the white spots.

Well, we're all different and how our brains are wired can affect how we see things. It is known that people with schizophrenia don't see optical illusions in the same way most people do.

Not saying you have schizophrenia, but if you don't see optical illusions at all or very faintly then I guess it's not "normal" in the statistical sense. Most people do see optical illusions.

Are you looking at it on a phone screen or something larger?

Usually this works for me but right now it's completely still for me too. Might be depending on image size, contrast, brightness, fatigue...

It doesn't work very well from phone size.
