These days I am partial to tortoises. The theory of evolution has originated in the Galapagos which are full of turtles despite Darwin's HMS Beagle using them for food. And the infinite regression is sometimes expressed as "Turtles all the way down," https://en.wikipedia.org/wiki/Turtles_all_the_way_down . Escher had some turtles in his Gravitation, but I think infinite turtles deserve further sketching.quantAndHold wrote: ↑Tue Jan 02, 2018 12:48 amI drew a sketch of a frog on the back side of a sketch of a tortoise. I think I need to make up my mind on the reptiles vs amphibians question for my next art project.
