    A trick for easily shifting your perception:

    First imagine the cube is sitting on the ground and you are looking down at it from slightly above and to the right (this is the way most people will initially perceive it, because it is the most familiar).

    Then imagine the cube is instead attached to a wall or perhaps a ceiling and you are looking up at it from slightly below and to the left.

      Or better yet - this helped me more because I couldn’t get what you were saying until I saw it - is that you can think of either one of two faces that the cube can sit on. Before I explain which faces I am talking of, I have to note that a cube face can be described by its diagonal, which is what I have to do to explain this in words and the second one is that in a drawing of a cube there are six peripheral intersection points(three to the right and three to the left) and two inside points a right one and a left one. So these two faces the cube can sit on are:

      The first is the face whose diagonal starts from the bottom left peripheral point and reaches the right inside point

      Then the second face is the one that spans from the left bottom peripheral point until the right middle peripheral point.

      This helps me change perspective instantly.

    POV: The second one is just wrong and you all know which one I mean

      Were you able to see it? It was driving me crazy in the middle of my lecture, so I did what a sane person does and made a meme out of it.

        Yes I am able to see it, if I concentrate on the corner in the back or the one in front I can switch with a little focus. But seeing it trying to change in the middle if me watching it feels extremely weird

      I don’t think so. I think it’s how you perceive yourself looking at it. Are you under it or above it? I think since it’s 2D, on screen, etc. most people perceive it as something they’re above. There’s also a common viewpoint for 2D representation of 3D objects so the brains would be influenced by that, kind of like how a map’s top edge is always North.

      That’s a good explanation, you can either view it as above or below the top back vertex, whatever your brain choses to decide! I wonder if there is actually any more thorough explanation of this.

      Thank you - your description is the only one that allowed me to see the “other” perspective. If I really focus on the “wrong” bottom face and bottom left vertex I can see it the wrong way for a short time but the instant me brain notices the top right vertex it flips back.
