It's impossible in our everyday space, since it's torsion-free. However I've seen crystal systems that had properties similar to what those stairs would produce.

Once you stop assuming that the white surfaces are all perfectly horizontal, there is no problem with the picture.

I like that picture. It looks like the stairs go around in a circle and join back up again. It would be impossible to make for real.

I have a book completely of his art work like that.
You'd be amazed, it's all of the kind.

Specially math-oriented people always enjoy of Escher in drawings as Bach in music.

You need explanation and here you are. All corner not in right angle. See top-left and low-right stair they are not collateral as example.
Many people fail to use his eyes, deceive themselves that all corner are in perfect rectangular. Easy illusion I say.
