Most of the spirals presented here (except for Spiral 5 and Spiral 6) have been derived with the help of one general procedure:

to spiral   :size   :size.incr  :angle  :angle.incr
; Since the procedure is a recursive one,
; some sort of a Stop Rule should be included here,
; that is, you should carefully define the condition when
; the procedure stops.
; Otherwise you'll have to use some sort of a fire extinguisher,
; Halt button, for example, which is not the best way
; to control the situation
fd :size rt :angle
spiral   :size+:size.incr   :size.incr   :angle+:angle.incr   :angle.incr
end

But, if you want to cook your own cake, add to this recipe one-two teaspoons of colors, a spoon of diligence, fantasy - up to your taste - and enjoy!
