M. C. Escher Waterfall

From one Dutch artist to another, I love this guy.  M. C. Escher.  We had the privilege of wandering around the square upon which his home is located on a beautiful day in den Hague, Netherlands.  I loved visiting there, by the way.  One reason was that the land was filled with 'my people,' freckly, frizzy-headed people.  Just made me happy to be among my own.

Anyway, his home is now a museum, and we delightedly took a wander through it, all of its glorious three or four floors, jam packed with his work.  

Here's his Waterfall.  One of my favorites.

Which way is it flowing, anyway?
