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.
