Happy Escher Day

[featherynscale]

"At high school in Arnhem, I was extremely poor at arithmetic and algebra because I had, and still have, great difficulty with the abstractions of numbers and letters. When, later, in stereometry [solid geometry], an appeal was made to my imagination, it went a bit better, but in school I never excelled in that subject. But our path through life can take strange turns."
MC Escher, born on June 17, 1898; Dutch artist renowned for his geometric art
