The Mandelbrot set in brainfuck.
To run, use ./bfint.py mandelbrot
Tests points in increments of 1/16 from -1.9375+1.9375i to 1.9375-1.9375i. Never uses undefined behaviors of '-' instruction on cells containing 0. Implemented on 1 byte-sized cells.
By default, the program uses 9 iterations to generate an image of the set. To get a sharper image (well, as sharp as you can when you're using test points every 1/16th), try adding more '+' commands in the 'mandelbrot' file where it says "number of iterations" next to 3 '+'s. (line 18)
