When playing with some of these examples, to get a circular picture:
- The shape you're making a circle out of must end up approximately where it started. (Use polygons... draw a line and then turn 360-divided-by-the-number-of-lines degrees.)
- The cirlce should go around 360 degrees. (If you repeat 10 times, turn 36 degrees each time; if you turn 5 times, turn 72 degrees; if you turn X times, turn 360 divided by X degrees.)
The simplist of all turtle-graphics examples.
Another complex and beautiful picture. A few variables and strings assigned at the top of the program let you quickly and easily change the message displayed.
