From the site above “Logo is a programming language that was created in 1967 that was a fairly popular teaching tool in the 80s. It has taken on many forms, appearing on platforms such as the IBM, Commodore 64, MSX, Atari, and Apple II computers. Variants of Logo have been used to guide robots and build shit with Legos. It is still around today, but it is largely defunct. Although it bills itself as a programming language, Logo is really more of a CAD. By inputting text commands into a prompt, the user moves a triangular cursor known as a turtle around the screen to create squares, circles, and other shapes that can be made in Microsoft Paint in much less time. There have been dozens of version of Logo, each with slightly different commands and interfaces. This was even true on a single platform. The Apple II offered versions such as Apple Logo II, Terrapin Logo, and LogoWriter. “
