My Fibonnaci Zentangle

My friend Stephenie turned me on to Zentangles. I saw the potential for combining the Fibonacci grid that I use in Growing Patterns: Fibonacci Numbers and Nature and zentangling. I just need to add the spiral.

Richard and the boys are giving me no end of ribbing about the fact that I spend time on the internet researching new “tangles,” which look to them like plain doodling. The final straw was my insistence that I had “messed up” and went to get the white out.
