Turtle Art is an activity with a Logo-inspired graphical "turtle" that draws colorful art based on [http://wiki.laptop.org/go/Scratch Scratch]-like snap-together visual programming elements.

Turtle Art is an activity with a Logo-inspired graphical "turtle" that draws colorful art based on [http://wiki.laptop.org/go/Scratch Scratch]-like 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 [[#Exporting to Berkeley Logo|Berkeley Logo]]. The [[Activities/TAExperimental|experimental version of Turtle Art]] also has a (limited) facility for sensor input, so, for example, you can move the Turtle based upon sound volume or pitch.

A [[Activities/Turtle Art/Templates|portfolio feature]] lets you use Turtle Art to create multimedia slide shows from material retrieved from your Journal. The basic idea is to import images (and eventually movies, audio, and text files) into slide templates, not unlike Powerpoint, and then show a presentation by stepping through them. The portfolio includes the typical major functions of presentation software: an editor that allows text to be inserted and formatted (this is largely incomplete), a method for inserting images (from the Journal), and a slide-show system to display the content. What makes it a bit different than tools such as Powerpoint is that you can program your slides using Turtle Art blocks. Turtle Art also has an export-to-HTML function so that presentations can be viewed outside of the Sugar environment.

You add blocks to your program by clicking on or dragging them from the palette to the main area. You can delete a block by dragging it back onto the palette. Click anywhere on a "stack" of blocks to start executing that stack or by clicking in the Rabbit (fast) or Turtle (slow) buttons on the Project Toolbar.

[[File:Keyboard.png|400px]] Q: How do I cast keyboard input to a string? Looking at the source your are using ord() to fetch the input... is there a way to convert that back to string before showing it? ANS: Use chr(). See the example in the illustration.
