I don't get it.

Stare at the center for a while.

what sorcery is this?

>>19440
Okay so your brain is designed to block out worthless information so stuff that doesn't really stand out is ignored and the whole picture is really blurry so the whole thing ends up being ignored until you have a white screen

>>19441
That doesn't happen for me :/
When I look at it the picture almost seems to focus for a moment, then goes back to being blurry (without disappearing).

>>19442
Same

I can make it very pale, but not white.

>>19442

Whenever your eyes twitch it becomes visible again. You have to keep them pretty still for about 10s or so.

Look at this photo, and then take a step back and look at it.

Looks to me like there's a hand in the bottom left that's flipping me off.

Similarly to >>19433 the pink dots faded away until I only saw a single green one going around.

Strange. Possibly because of a mild case of red-green colorblindness, I end up seeing something like this.

>>19527
Works just fine

Everybody loves this one.

Right?

>>19587

I see right, but I can change it to left if I focus.

>>19539

What is interesting is that there is no green dot.

>>19650
That's not that bad. It works fine if the loops are really twisty. Or maybe if the square is twisty.

I guess so. I'm running out of good optical illusions though. Seems like 90% of the ones on Internet are just >>19407 redeux.

Are the lines parallel, or sloped?

Oh I actually saw ASCII art of this one once. Let's see... nah I can't find it. It is like, sort of tilting rows down which ascii marbles roll, and it's all Unicode and stuff. Looks continuous even though it's divided into separate lines.

That almost gets it. You can see the effect subtly at least.
