There’s so much JPEG artifacting in the original. All of it, and I mean all of it, could have been avoided, at much smaller file size, by setting tile size to 16 instead of 15.
Color variations in white tiles, it seems. When you look close, the brain compares shades of white to the neighboring black. When you look far away, brain focuses on larger patterns.
For those struggling get rid of the high frequency information. Easiest way is to increase the viewing distance.
How does that help? There is definitely a tiny cat but can you see a big one after Gaussian blur?
I’m going to plead temporary insanity - I swear I saw a big face when I put it across the room. Now I don’t. 😄
Here’s another example. Look at this grating from several feet away.

How does it work?

that’s what it is, I’ve made one before. basically grayscale image faintly on a black and white pattern, doesn’t need to be checkerboard.
Magnets, maybe.
Spray a little water on it and the illusion stops working, so yeah it must be magnets.
That makes the tiny little cat harder to see
There’s a little 😺?
