I have a koi pond in my backyard. The Spring here in Phoenix is
lovely. While sitting with a cup of coffee, I looked around for a shape that I could create
a pattern with and found this cactus leave shape. I have found that many times if I just focus on a small area in  front of me for more than 3 minutes, I can begin to see things I missed. This process of relaxed focus is really the ZEN part of this kind of doodling and creating new patterns.
