Inspired by the Logo programming language, TurtleArt is designed for children and adults to make images while exploring geometry and programming. The user specifies a sequence of commands by snapping together puzzle-like blocks. The blocks tell the turtle to draw lines and arcs, draw in different colors, go to a specific place on the screen, etc. There are also blocks that let you repeat or name sequences, while other blocks perform logical operations.
The Windows and Mac versions of TurtleArt still exists and is available for free upon request. Visit www.turtleart.org to obtain your copy and see sample art work.
