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 [~~http://www.cs.berkeley.edu/~bh/~~ Berkeley Logo]. Turtle Art also has a (limited) facility for sensor input, so, for example, you can move the Turtle based upon sound volume or pitch.
