Remember Escher

Have you ever seen this amazing picture?

 Or this one

They were created by M.C Esher - famous dutch artist.

 I have seen the pictures earlier, but lately fall in love with tessellation.
Some quilts have the same design.
I tried to make a simple pattern.

I was wandered Escher was born today.
You would say: Everybody has a birthday.
Amazing fact is that I have birthday, too.

Happy birthday to me!
