The goal of &kturtle; is to make programming as easy and accessible as possible. This makes &kturtle; suitable for teaching kids the basics of math, geometry and... programming. One of the main features of &turtlelang; is the ability to translate the commands into the speaking language of the programmer.</para> <para>&kturtle; is named after <quote>the turtle</quote> that plays a central role in the programming environment. The user programs the turtle, using the &turtlelang; commands, to draw a picture on <link linkend="the-canvas">the canvas</link>.</para> <sect1 id="what-is-turtlelang"> <title>What is &turtlelang;?</title> <para>&turtlelang;, the programming language used in &kturtle;, is heavily inspired by some of the fundamental concepts of the &logo; programming language. The first version of &logo; was created by Seymour Papert of MIT Artificial Intelligence Laboratory in 1967 as an offshoot of the LISP programming language. From then many versions of &logo; have been released. By 1980 &logo; was gaining momentum, with versions for MSX, Commodore, Atari, Apple II and IBM PC systems. These versions were mainly for educational purposes. LCSI released <application>&Mac;&logo;</application> in 1985 as a tool for professional programmers, but it never caught on. MIT is still maintaining a site on &logo; which can be found on <ulink url="http://el.media.mit.edu/logo-foundation/">http://el.media.mit.edu/logo- foundation/</ulink>.</para> <para>Today there are several versions of &logo; around which can easily be found on <ulink url="http://el.media.mit.edu/logo-foundation/">MIT's &logo; site</ulink> and by a simple <ulink url="http://www.google.com/search?q=logo+programming+kids">Google search</ulink>.</para> <para>In comparison with most modern versions of &logo;, &turtlelang; implements only the basic commands best suited for the educational purposes of the language, and does not try to fulfill professional programmer's needs.</para> </sect1> <sect1 id="features-of-kturtle"> <title>Features of &kturtle;</title> <para>&kturtle; has some nice features that make starting to program a breeze.
