LOGO and Turtle Graphics

I'm sure you all have fond memories of being a 7-year-old child programming in LOGO at school (at home we mostly used BASIC and Z80 or 6502 ASM). I remember that some spoiled rich kid even had a real turtle, like this one http://www.obsolete-tears.com/hist/promobile/tortue.jpg

So, here's a small LOGO program:

to shitbrix :angle
repeat 4 [ fd 30 rt :angle  fd 10 rt :angle fd 20 lt :angle fd 10 lt :angle fd 20 rt :angle]
end

If you call it with the parameter 90, it draws:

shitbrix 90
 _   _____ 
| | |  ___|
| |_| |___
|____  _  | 
 ___| | | |
|_____| |_|

With parameter 120 it draws:

shitbrix 120

        -
   ___ /_\____
   \  /   \  /
    \/     \/
    /\     /\
   /__\___/__\
       \ /
        -

Lisp and LOGO are both toy languages. The difference is that LOGO users don't pretend otherwise.
