Escher's flatworms and wheel creatures

"Flatworms" by M.C. Escher:



Planarians are possibly the single easiest animal in the world to draw. Sure, there are other animals with just as simple a shape, but those don't have little googly eyespots. If you draw a pointy lump without any googly eyespots, nobody is going to think it's much of anything.





I've loved Escher's "curl up" creatures since I saw them in a book as a kid. They look so much like some sort of cambrian lobopod (like Opabinia or Anomalocaris), but they have those delightfully creepy little human feet.
