Sorry 😳 It all comes from being an art major and art freak. M.C. Esher was a dutch artist who used a lot of mathmatical equations in his art work and did some really neat stuff with symmetry. He is considered the father of graphic arts. Here are some examples of his work…..
Butterflies

Lizards

Geese and Fish

Warriors

Ducks and Fish

Butterfly rose window

Who’s drawing Who?

That’s why I found this one of the bunnies so amusing!
