What am I supposed to be seeing?

Should I be further away or closer?

Keep staring at the cross but try to be aware of what the faces look like in your peripheral vision. I think closer is probably best but experiment till you see something interesting. You can look straight at the faces for the next cycle or two if you want - it doesn't affect the illusion.

This all reminds me how utter shite our vision really is and how much we can thank our brains for assuming it's better.

The color bars work because our color resolution is way worse than our luminance resolution and so the colors bleed over into each other while our luminance and edge detection says there's hard lines. If you zoom in really close you can see the blue tinted green for what it is, if you zoom out a bit more the spirals become obviously different. This is part of how JPG compression works. It separates out the luminance from the color and then throws away a ton of the color since it's not really needed for proper perception of the scene.

I see weirdness and I have to look. I can't keep my eyes fixed on the centre.

Especially the eyes.

Can you see it? I was not able to until it was pointed out to me. Now I cannot unsee it.

I thought the little pebble was supposed to look like a severed bird head looking left. Oh it's the end of the cigar. Or a rabbit face looking right.

It took me about half a minute, and that was after I skimmed the last few posts and read something about a cigar.

Like many of the two image illusions like this I can get it to flip back and forth by thinking about what it's supposed to be, so even though I know what it is, it becomes an indent in the brick if I think "this shading is indented brick like those next to it and a grey turtle head popping out."

It's clearly a snapping turtles head and not a bird.
