== Introduction ==

Turtle Art is an activity with a Logo-inspired graphical "turtle" that draws colorful art based on snap-together visual programming elements.

Turtle Art is intended to be a stepping stone to the Logo programming language, but there are many restrictions compared to Logo. (Only numeric global variables and stack items are available, no lists or other data-structures. The conditionals and some of the functions only take constants or variables, not expressions. Limited screen real-estate makes building large programs unfeasible.) However, you can export your Turtle Art creations to Berkley Logo. The ~~sensor~~-~~enabled version~~ of Turtle Art also has a facility for sensor input, so, for example, you can move the Turtle based upon sound volume or pitch.

The [http://git.sugarlabs.org/projects/turtleart/repos/arduino-support Arduino fork] of Turtle Art also has a facility for sensor input, so, for example, you can move the Turtle based upon sound volume or pitch.

Turtle Art is in the same tradition as Etoys, Scratch, Lego Mindstorms™, and Lego Microworlds™.

Turtle Art is used extensively in Sugar deployments and numerous materials for support in the classroom have been developed. Of course, since Turtle Art is a Logo derivative, many of the classic Logo exercises are well suited for engaging students in Turtle Art. For example, Tony Forster has been [http://tonyforster.blogspot.com blogging about a wide variety of Turtle Art activities]. Gonzalo Odiard has written a [https://sites.google.com/site/godiard/TurtleArt.ppt?attredirects=0&d=1 short introduction to Turtle Art].

Turtle Art will let you export your project as PNG, HMTL, SVG or Logo. In other words, you can use Turtle Art to make presentations and as an SVG generator.
