Spirals: A Shape That Radiates

This challenge closed over 2 years ago.

The Challenge

Spirals, spirals, spirals! The last challenge focused on radiating patterns, for this one I want to focus on spiral shapes, where the images allow the spiral shape to stand out more than the pattern. This may not be as easy as you think as spirals are actually quite complicated. (As I found out when researching this topic!)
For the definition, I chose to use Wikipedia, which starts out with a simple explanation and moves on to more complicated examples, like an archimedean spiral. But, I will try to keep it simple: “In mathematics, a spiral is a curve which emanates from a central point, getting progressively farther away as it revolves around the point.” (http://en.wikipedia.org/wiki/Spiral) A helix may or may not be a spiral, depending on whether or not the “loops” have the same diameter. So if you submit an image of a helix please make sure it is a conical helix with a central point. (The double helix in DNA is not conical).

Some examples would be spirals found in sea shells, vortices (vortex), unfurling plants, expanding smoke rings which have a central point and other similar things.

When I am moderating, I will ask myself if I can “see” a single, unwinding line in the image. My apologies out there to the mathematicians out there, for whom formulas are required to determine types of spiral shapes!
