Sierpinski triangle/Graphical is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.
Produce a graphical representation of a Sierpinski triangle of order N in any orientation. For example, the Sierpinski triangle of order 4 should look like this:
Icon and Unicon
The following code is from program by Ralph E. Griswold that demonstrates an interesting way to draw the Sierpinski Triangle. For an explanation, see "Chaos and Fractals", Heinz-Otto Peitgen, Harmut Jurgens, and Dietmar Saupe, Springer-Verlah, 1992, pp. 132-134.
