The curve of life: Abstract Thursday

I love spirals and was very impressed with this one I saw as part of the Christmas lights decoration.
The spiral is fundamental to the structure of plants, shells, and the human body. They are just everywhere.
I first saw this particular spiral at night and I knew I had to go back there with my camera, either at night or early enough in the morning before it got light. Since I'm a very early bird, the choice was easy!  It's also a fairly quick area to get to on the metro and to get there and back within the hour. 
Joining the Abstract Thursday challenge today!
Thank you Ingeborg for hosting.
