Fibonacci spiral 2

First 67 Fibonacci numbers. Geogebra doesn't let me add any more precise points on intersections of lines
Pretty amazing to think that the sides of the last square are 44,945,570,212,853 times as big as the first one.... The surface is 202,010,428,175,849,920,368,736,056 times as big! :O
