The following programs are a collection of examples most of which I have created
for my own amusement or as teaching aids. You are welcome to download copies
and play with them. You may also place copies on your website as long as you
add a link to this page and e-mail me details of where
you are using them.
If you switch to the procedures page using Ctrl + F or Pages | Procedures you will see that most of these examples use procedures. if the example has no procedures then right click on the turtle and see if there is any code programmed directly into the turtle.
Colours can also have code associated with them. Click on the Paint Brush button to view the colour pallet. Any colours with a black dot in the center of the colour has logo code programmed into it. Double click on the colour to view the associated code.
Note: these example programs are written using MicroWorlds Version 2.05

The heading names were created using Paint
Demonstrates using turtles as text
|Inspired by the online essay going
Note this version uses:
talkto [t1 t2 t3 t4 t5 t6 t7 t8 t9 t10 t11 t12 t13 t14
t15 t16 t17 t18 t19 t20 t21 t22 t23 t24 t25 t26 t27 t28 t29 t30 t31 t32
t33 t34 t35 t36]
everyone [repeat 30 [fd 4]]
because each turtle moves forward at the same time. Using everyone [repeat 30 [fd 4]] moves each turtle one after the other which spoils the effect.
Inspired by the online essay going
Demonstrates control of multiple turtles at once
Inspired by the online
essay going in circles
