A Julia Sets Generator coded in C.
A Julia Set is the fractal defined by the sequence z²+c where c is a complex number.
Compile it with gcc and parameters -lpng for lib png.h and -lm for math.h (gcc fgen.c -o fgen -lpng -lm)
./fgen <side of square image> <number of iterations> <power p of z in the sequence z^p+c defining the Julia Set (usually 2)> <Re(c)> <Im(c)>
This one is given by
./fgen 400 400 1 .355534 -.337292
(and yes this is where I took my profile picture ;)
