A Turtle is an educational robot originally created as part of the Logo programming language. Originally the Turtle was a physical robot controlled using Turtle Graphics (a part of the Logo language). With advances in screen graphics, a virtual Turtle became prevalent. Originally, the Turtle and a Sprite were different. LogoWriter and RoamerWorld blurred the distinction by allowing programmers to change the shape of the virtual Turtle. We keep the distinction.
