Now, with both on the screen, try to simultaneously see one facing left/down and one facing right/up.

You can also purposely avoid seeing any intended depth and it'll look like a weird diamond someone drew

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.

The anime is Great Teacher Onizuka (GTO for short), in case anyone was wondering. Can recommend it, it is funny.

I tried to see the difference, then saw the difference, and now I can't go back to the first thing I saw.

Monke brane and senses, well adapted to survive in the savannas of Africa, encounters math and gets baffled.

EDIT: Visualize the apes at the beginning of 2001: A Space Odyssey, scared but touching the monolith. Now imagine that the monolith is the square root of minus one.

That's because only the bottom and top layer intersect. And you can't make more than two parallel layers intersect in 3d space, so yeah.

Now that you have successfully gotten your brain to flip the cube in to the different orientations; now while it is flipping flatten it to a 2D shape with a small square in the middle.

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.

Just 2?

Like the 5 circle multi directional tube.

Right hand rule.

I feel like i’m being pranked. Isn’t it a cube? Equal sides? Are you seeing a different shape?

Oh okay normal and one as if from below. I was so confused.

Rotate your phone 45 degrees and it's a rupee from Zelda

Tesseract says hello

Now command your brain to see top and bottom cubes differently.

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.

You really want to make your brain hurt? A cube is the side of a 4 dimensional object.
