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.
