      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.
