Playful Invention Company
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.
