accomplishments? unless your name is mandelbrot or sierpinsky or
something, you simply don't have any accomplishments in fractals.
Writing a fractal program is trivial, unless you design a new
algorithm yourself. If you call programming a fractal an
accomplishment, then here's mine:

A javascript animated sierpinsky triangle.

TO show how simple programming a fractal really is, here's a fractal
in postscript I picked up somewhere recently, probably on this group:

save to a file and view as postscript.
