turtle text

nam shub can output graphics via a modified turtle graphics paradigm taken from the computer language LOGO but applied to text output.

in LOGO lines can be drawn via simple commands that move a pen (turtle) on the screen:

LEFT 90 FORWARD 100 LEFT 90 FORWARD 100 LEFT 90 FORWARD 100

the above draws a square by moving forward and the turning left by 90 degrees after each line segment.
