Oh wow! It took me a few seconds, but there they are.

I had to look at the big picture to find them, but once I did I was able to see them in the little picture (though not as well).

I couldn't see them until I scrolled down past it quickly, I guess that made the vertical lines stand out more.

What's maybe interesting is that once I saw one row, I didn't immediately see the other rows.

Yeah, sometimes it's the case that when I see one, I can't see its neighbors. And other times it's not. WEIRD!

I read some of your foolish scree, then just skimmed the rest.

Resolution seems to have something to do with it. On my phone I have to zoom in to a circle then back out but once I look away it's rectangles again. Computer monitor on the other hand the circles are massively apparent.

I don't know why, but I find it much easier to see the circles in the bottom two rows. It gets progressively easier as you go down for me.

What's really weird is the circles were obvious for me and I wondered why slimshady was giving a hint under the spoiler tag. I showed the Mor-man and he didn't see the circles at all, but they were so profound to my vision.

I investigated it in the photoshops. If you guessed that the circles were the same horizontal lines just rotated 90 you'd be right.

My guess is the illusion has something to do with background/foreground flipping.

While investigating I discovered this, which besides screwing with your vision if you stare long enough produces an interesting gradient effect if you stare at one spot and move closer and further away.

Tell the Mor-man to concentrate on one part of the image that has vertical lines, and then follow the path formed by joining together the end of each vertical line with the nearby end of its neighbor.

If you erased all the horizontal lines in the image, you'd just be left with a bunch of vertically-striped circles.

That's insane. I don't see a gradient in the big image, but in the thumbnail I do. That's without doing any staring or moving, just at a glance that's how it looks.

Oh yeah, good point.

On my phone the thumbnail vibrates, too. On the laptop it does not. They both have the gradient.
