This is my use of the turtlehack library. Results will vary.
This is my code:
import turtle
from turtlehack import *
import random
fido = turtle.Turtle()
canvas = turtle.Screen()
canvas = bgcolor("black")
for i in range(20):
random_circle(fido, 3, max_size = 100)
fido.color(random_color())
fido.penup()
random_location(fido, 50, 70)
fido.pendown()
dotted_line(fido, 50, 12, random_color())
