Also known as "that game where you draw using the Turtle", Logo is described by the Logo Foundation thusly: "The Logo programming environments that have been developed over the past 28 years are rooted in constructivist educational philosophy, and are designed to support constructive learning." Uh, right. So basically you issue text commands to draw on the screen by making the little turtle guy move around. :) An interesting game-like program to be used primarily as a young child's first "programming" experience.
