Don’t tell there’s another one

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.
