Algae

I just read an article on patterns in nature this morning. On my ride back from volleyball practice, I spotted this arrangement of algae in the canal next to Cherry Avenue. I liked how the shadows played across the green texture of the algae and water and brought attention to the droplet rings on the right side (which I made sure were in the correct place according to the rule of thirds - thanks to my daughter's photography class which has reinforced those compositional rules i learned in my photography classes so many years ago).
