Golden Angle

I'd rolled up this plastic binding strip months ago not really thinking about what to do with it later.  I took the rubber band off of it a couple days ago just playing with it and noticed the spiral pattern it was making.  I realized it had set in an elliptical shape rather than a circle and after unrolling it formed this pattern. Although not specifically the same as the golden angle, it sure resembles it to a degree.

For those of you who don't know, the golden angle is the smaller of the two angles whose total is a complete circle if the ratio between the two angles was equal to the ratio between the larger angle and the complete circle.

It is most apparent in tightly growing clusters like pine cones and seed or flower heads but also has a role in the growth pattern of leaves as was shown in the picture of my agave plant that I had years ago as posted in the Gardening Forums, said picture was actually an old one from this blog.
