and then people think we can absolutely trust our perception
I know they're concenteric circles, and once I'm able to convinve my brain it sees it that way it switches what it identifies as the void space and goes back to being a spiral.
This is the curse of the Spiral Menace.
"They're circles, damn it! Perceive them properly!"
My brain:

Well I hate that, lol

Best circle I can do by hand on my phone... while pooping. You're welcome.
My initial reaction was "this is a circle on top of a spiral, what does this prove?"
It blows my mind that even when you're looking for it, you STILL need to use logic to disprove the illusion.
That red circle is in blue the entire time. It never touches either black & white circle that it is between.
Oh sure... THAT one is a circle, but the rest are clearly spirals!
Why'd you draw a circle around a spiral?
I am also pooping and found this helpful. Thank you for your service!
I am also pooping and found this thread amusing! We are all connected in this moment, at one with nature and each other
Pooping here, too....
I, now, must poop.



you deserve this:

Even the thumbnail still looks like a spiral.
This one is stroooong.
Sorcery !
Mad. Brains are weird.

If I close one eye they look like circles
I actually saw them as concentric circles first, and the spiral effect is subtle but I can get it if I stare at the very center of the image. My vision is really bad on one eye, so I guess that might have something to do with it.
That does seem to help, but I can tell my brain is fighting me the whole time.
