Pretty amazing stuff. I've had a book of his since I was a kid. Its amazing how this dude's brain works.....

What's really amazing is that he didn't start drawing till he was 54 years old and worked as a merchant marine. He took pictures everywhere he went and after retiring started drawing copies of the pictures he had taken years later.
His artwork incorporates advanced mathematics and is truly impressive in person.


Yeah, I've heard of him.

 

I've always liked the tesalating patterns he draws. Truely unique.

 

I think hands drawing hands is one of my fav's
