Fibonacci spiral

The theme this week is for SPIRALS. This is my first contribution. It's not so long ago that I learnt about  the Finpbinacci sequence and how these numbers echo so  much in the natural world, especially  pine cones. It made me look a bit closer. 
Th sequenece is basically the sum of a number and its previous number
0,1,1,2,3,5,8,13,21,34......etc
Its fascinating how often this number sequence is found in natural objects.

I've been needing to practise  more with Macro so it was a good exercise.

Windy day, local walk. For some reason I have a sore throat . Not sure how as I've not been nearer anyone to catch a germ!
