Scurtle

Scurtle is a system for working with Turtle Graphics. Turtle graphics are 2-dimensional line graphics drawn in a relative manner.

Imagine you have a turtle on a canvas, with a paintbrush on his tail. If his tail is up, he is simply moving, and the canvas remains blank. If, however, the turtle has his tail down, he is drawing, and a line is created underneath him as he moves.

The turtle can turn left or right, changing which direction he is facing. When he next moves again, it will be in this new direction. Unlike Cartesian Geometry, where each point is represented by a set of coordinates, lines in turtle geometry are represented by a combination of an angle and a distance, and depend on previous moves.
