Doodling’s a beautiful thing. Whether you’re thoroughly engaged in it, or absentmindedly filling the corner of a paper, it’s a wonderful activity to get lost in. As I filled my divided page with patterns, I started thinking about a particular style of doodling referred to as Zentangle®. Examples are everywhere. Thousands of images are on Pinterest alone. And while they can be quite beautiful, I was curious as to why they were considered distinct from other doodles, to the extent of having their own trademarked name, and a pending patent application. I started nosing around and discovered it’s definitely a controversial issue.
