In Ebru, this is a traditional pattern called Zebra. It could almost pass as another traditional pattern called Antique. The difference between the two is the size of the Stones thrown on top of the Gelgit. Larger stones make it Zebra. Smaller stones make it Antique.
I teach the history and variations of traditional patterns to my students because I feel when on knows the past ~ when one understands how something got to where it is ~ only then can one bring the story to life.
