Turtle Geometry exercises

Thursday 22 December 2011 at 17:05

Exercises and examples from chapter one of Turtle Geometry by Abelson and diSessa implemented in javascript. Kinda blown away by this book: only on chapter one and this page already offers a pretty fun playground for exploring geometry and rudimentary graphics programming.

Click some of the links below for examples and inspiration. You can also type commands into the form below the turtle's sandbox. Commands you type will be saved in the history below the sandbox.

Pen controls include penup, pendown, pensize pixels, and pencolor color. Any CSS color name or hex value will work for color: Wikipedia: Web Colors
