I just uploaded the new version. It generates almost the same image; so, I do not update the image. The new algorithm is supposed to give 14 correct decimal digits; I have tested it with Mathematica and with Maple. Also, I expect, it can be used in any other programming language with minimal modifications. I had run it under Unix and under Macintosh; I expect it to generate the same image with other operational systems too. The algorithm is optimized for size of code and for the human readability (not for memory and not for speed), but it works! One can make the similar algorithm for other values of base, not only for b=sqrt(2). Please let me know if you find it useful, or if any problems with compiling, or if any questions.
