The Fibonacci spiral

I've come to the stage in my future life project where i need to think about producing scale drawings of the structure i have designed. My mum is a maths teacher and reminded me of the fibonacci spiral and that it might help me to produce a perfect spiral.

The fibonacci sequence is as follows-
1, 1, 2, 3, 5, 8, 13, 21, 34, 55 and so on...

This is reached by adding the first two numbers to get the third, the second and third to get the fourth, the third and fourth to get the fifth etc....

1
1+1 =2
1+2=3
2+3=5
3+5=8
5+8=13
and so on......

So when u arrange a series of squares like this with these lengths, you get the perfect spiral!
