Hi Everyone, The source code for skulpt, and my implementation of xturtle is also available on github at http://github.com/bnmnetp/skulpt. Skulpt is a Javascript implementation of the Python language that runs in the browser. I spent a good chunk of my Sabbatical a couple years ago implementing the turtle code in Javascript and then writing a wrapper to fit it into the Skulpt environment. We, at Luther College, have used the turtle code pretty extensively in the context of our interactive textbook (http://interactivepython.org) for a couple of years now. This fall we have about 25 schools around the world using the book, so I'm starting to think its pretty stable. :-)
The turtle module is still missing event processing functions such as onKey, onClick, etc. But I think the vast majority of the functionality is there. If you do find something missing or have feature requests, please let me know.
