Is this even an optical illusion?

2D pictures can't be optical illusions.

warped wood where left is coming out at the viewer and right is going in, but at this angle it looks like a perfect square?

Sure they can. In fact it wouldn't be a stretch to say that the vast majority of art since the late 15th century has made prominent use of optical illusions to provide a sense of realism.

That particular Escher image is not an optical illusion. You could build it.
The impossible part is that the various figures each have a "personal" gravity. We couldn't do it even if we could generate gravity. The figures top-center stand at right angles even though they're adjacent.

Some Escher images ARE illusions. "Ascending and Descending" and the closed-loop waterfall are examples of the Penrose Triangle. They can be built "in solid" but only viewed from one particular angle.

You must think the latest capeshit movie cgi is an optical illusion too. Brainlet.
