So my imperfect understanding is they formalised Escher's shading tricks. And so systematised making the impossible look possible. Which is what magicians do by gaming our perceptual firmware. Which is the reverse of what we do when debugging a nasty corner case. The observed behaviours seem impossible, until our perception of possible causes realigns.

Are they tricks, or are they topological, non-Euclidean integrations? My guess is as the occipital is not 3-D, but dual input 2-D that splinters into thousands of topological units, that our 2.5-D (it's not 3-D in the slightest) vision slammed together on the primate face for parallax response times is uniquely suited for plastic revolutions in dimensions beyond 2-D, not just 3-D.
