<h2>About Turtle Graphics</h2>
<h3>History</h3>
<p>
Turtle graphics were originally developed as part of the Logo language
developed
in 1967 at Bolt, Beranek and Newman (BBN), a Cambridge,
Massachusetts research firm, by Wally Feurzeig and Seymour Papert.
There have been several attempts to commercialize
కుంచిక graphics for small children including the Terrapin Turtle and Apple
Logo Graphics using an Apple ][ computer. Most implementations
of Turtle Graphics did not include a full implementation of the Logo language.
</p>
<h3>History of This Page</h3>
<p>
This project was forked from
<a href="https://github.com/bjpop/js-turtle">https://github.com/bjpop/js-turtle</a>.
This project had the basic కుంచిక graphic functions, the
<strong>animate</strong> function, the immediate execution
of the <strong>command</strong> line, and the editable
<strong>definitions</strong> area. This was the substantial portion
of this project, and overall had brilliant ideas.
</p>
<p>
Kirk Carlson added some కుంచిక functions and added enhancements to make
the project more of a code developent platform. It is hoped that this
project can help young programmers move from code.org and Scratch projects
to JavaScript projects.
