It’s an illusion. It’s a bit like the spinning ballerina, which can change the rotation it spins with the power of the mind… Shadows can truck our brains. Try to look at this picture slightly from the right and imagine the light source comes from top left… Maybe that way you will be able to see it like they are upside down.
But these are all clearly right side up…
Is this an illusion post or a troll post? Genuine question.
They are, but because of the lighting you can trick your brain into seeing them inverted.

The self shadowing ruins the illusion. An upside down plate will not cast a shadow on its own center.
I can usually see those double perspective illusions. Not here, it’s just too obviously right side up to me.
