Logo is a popular language used to teach simple programming by guiding the progress of a ‘turtle’ which moves around a graphics screen.
Despite Logo’s simplicity, complex pictures can be constructed, as the screenshot shows.
A new version is available — 1.4f (January 2009) - which contains some enhancements which have been requested and some bug fixes.
Simple commands can be used to make the turtle move in a straight line or change direction, and complex patterns can be built up from the simple commands using procedures and recursive techniques
