Iain Macarthur's Zentangle Portrait

My discovery of Zentangle art led to another incredible discovery: Zentangle Portraits. I stumbled upon the work of Iain Macarthur, who has several incredible illustrations of these portraits. My favorite one is pictured below

I think it's really amazing how geometric art can take on so many different meanings. Some might thing that geometric art  refers strictly to sharp clean edges, but I've been slowly finding that this is not the case. For example, Zentangle art is incredibly versatile but still comprised of  many different shapes, some that don't even have names. Geometric art has that same versatility.
