Fibonacci Infinite Spiral

A small test i did for the latest monthly challenge of our french motion design community called "Motion Cafe".
The theme here was "monochromatic geometry", so i tried to create a simple infinite loop of the well known "Fibonnaci spiral" (the "n" near each straight side represent the incremental number in the fibonacci's formula : Fn = Fn-1 + Fn-2
