Create 16 turtles Move forward 6 turtle steps
----------------- ---------------------------
cro 16 fd 6
Put your pen down Lift your pen (or turtle tail) up
----------------- ---------------------------------
pd pu
Turn right 90 degrees Clear all (erase everything)
--------------------- ----------------------------
rt 90 ca
Draw a square (if your Pen is Down - PD you will see square)
------------------------------------------------------------
repeat 4 [ fd 3 rt 90 ]
The above square has a side length of 3
Draw a cool pattern of 36 spiralling squares (if PD pen down)
-------------------------------------------------------------
repeat 36 [ rt 10 repeat 4 [ fd 3 rt 90 ] ]
What is 36 times 10? 360 degrees.
So you will have a complete
round the world circle of
squares.
Observer mode commands: ca, cro,
Turtles mode commands: fd, rt, pd, pu
Note: repeat is used in either mode, depending on what
