Each of these was made in a short program using the "turtles.jar" file from the April 15 link.
The jar file MUST be in the same directory as the files that actually create these designs.
I have included them all in a project called "one". I actually started a blank project in JCreator LE, and then immediately added the jar file and other beginning files as needed.
See if you can make your own designs.
I have included the code for the six-pointed star at the bottom of this page.

public void run() {
Turtle yertle;
yertle = new Turtle(120, 50); // draw bottom line
for (int k=1;k<7;k++){
yertle.forward(50);
yertle.right(120);
yertle.forward(50);
yertle.left(60);
}
yertle.hide();
}
