A vortex is an irresistable force of nature. You can’t see it without feeling the urge to travel to it’s center.
A vortex in your zentangle will draw the viewer’s eye.
Start each line on a side at a corner of the box, and draw it across the side. That is what creates the darkness at the center.
Example of the Vortex pattern.
very cool pattern!

Jackie, I did check out your Vortex before you deleted the post. I think you've made a good start. Paint isn't the easiest medium for this kind of tangle, but you had control of the curves. You should see some of my first attempts at some tangles, lol!
This sucks nuts
