Turtle graphics

Turtle graphics is a popular way of introducing programming to kids. It was part of the original Logo programming language developed by Wally Feurzig and Seymour Papert in 1966. You can find more information here. With the following lines, you can create this star from the example. 

from turtle import *
color('red', 'yellow')
begin_fill()
while True:
    forward(200)
    left(170)
    if abs(pos()) < 1:
        break
end_fill()
done()

With some changes, we could make this nice figure, it is really cool to see how it draws this beautiful pattern. 

colors = ['red', 'orange', 'yellow', 'green', 'cyan', 'blue']
p = Pen()
p.speed(0)
bgcolor('black')
begin_fill()
for i in range(360):
    p.pencolor(colors[i%6])
    p.width(i/100+1)
    p.forward(i)
    p.left(59)
end_fill()
done()
