Rock #40 Sprial Rainbow Dots

It's kind of hard to see in the picture, but the dots start in the middle and sprial around the rock.  The dots spread out the further away from the center it gets.  I want to try this technique again, but fill in the spaces, so it's more like a defined line. #GJRATA GJ Rocks & Art Treasures Abandonment
