If u see it tilted towards the bottom, try to look at it from bottom to up, and if u see it bottom to up try to see from the top to bottom (idk if that makes sense but thats how i find i can see them, tho ur brain quickly adjusts to the “default” whichever u saw at first), also blink…
Monke brane and senses, well adapted to survive in the savannas of Africa, encounters math and gets baffled.
Even knowing the other possible orientations I still had to force quite hard to see the cube change, once it did though it shifted between forms easily without much effort.
I feel like i’m being pranked. Isn’t it a cube? Equal sides? Are you seeing a different shape?
The way I tricked my brain into seeing the other perspective is I closed my eyes, flipped my phone 180, then looked at the image again. The cube was now upside down, even after flipping the phone back while continuously looking at the image.
Now command your brain to see top and bottom cubes differently.
I seriously spent 10 minutes trying to get this to work and as soon as I was righting this comment to bitch about it, it finally flipped.

It’s not a schooner. It’s a sailboat.
both still look the same to me only with different shaded sides
Focusing on the grey square makes it flip for me.
You really want to make your brain hurt? A cube is the side of a 4 dimensional object.
Funny how at first I had to look from one to the other to switch my perception of it, even though they’re exactly the same.
The anime is Great Teacher Onizuka (GTO for short), in case anyone was wondering. Can recommend it, it is funny.
And the cube illusion is the Necker Cube.
Just 2?
Looks the same to me.
Right hand rule.
Like the 5 circle multi directional tube.
You can’t just say that and not provide a link.
EDIT : Damn you autocorrect.
I couldn’t find an example on line. Every search I tried failed miserably. So I drew one with 4 circles.

Okay
Gotta love phones.
