[PyGame] Fibonacci graphics ideas?

[BashBedlam]

I don't know if this would be considered inspiration or not but it's kind of fun to play with

import turtle
turtle.speed (11)

def fib_generator (seed, start, length) :
	fib = [seed, start]
	for i in range (length) :
		fib.append (fib[-2] + fib[-1])
	return iter (fib)

for diameter in fib_generator (9, 13, 6) :
	for i in range (4) :
		turtle.circle (diameter)
		turtle.left (91)

turtle.done ()
