What if Maurits Escher turned to dry stone walling? What if he shaped his ducks and lizards and fish out of stone, making sure that every one had exactly the same shape? Would they be as easy to lay then as bricks or squared blocks of stones? Or would it be more difficult? I wonder.
Would it be just one big boring puzzle? And more importantly, would the repetition of the pattern drive clients crazy?
Now that I think about it, probably Escher knew to stick with drawing impossible interconnecting shapes rather than trying to make them in the three D world, and then end up having no one that impressed. Sometimes an impossible creation, that's taken an impossible amount of time, no matter how perfect it is, is not as interesting as something that merely involved fitting random stones together skillfully.
Rather, for the rest of us wallers, whenever an opportunity presents itself, keep striving to do the improbable, . You could surprise yourself how well you do and, hopefully, it won't look cookie cutter perfect.
