My tangle pattern "OOfos"

This pattern reminds me of a cluster of UFOs dancing through the sky. I don't know if it's still the fashion, but in my day the word was pronounced oo-foes. And there you have the title!

Usually before I post tangle steps I go through the ZT books and Freehand Doodle patterns and a few other places to see if anyone else has done it. The brain tends to glaze over after a while, and since I've been working on getting my Who's Where in Zentangle blog going, I went much faster than usual. Please let me know if someone else has done this one. It's awfully simple, but sometimes those are the ones that get missed.
