Here's mine, which does an ASCII mandelbrot, written as an ASCII mandelbrot, in C.
Oh.. and it also has interactive zoom functionality. (press the keypad numbers 1-9 to zoom in on the respective area)
int main(int argc, char* argv[]){ unsigned
char c='r';double x1,y,y1,t=0,q=78,r=22,x,
x2,y2,a,b,v;do{(c=='r')?(y2=-(y1=-1.6),x1=
-2.0f,x2=0.8):(c=='?')? c=0, printf("%f\
,%f:%f,%f",x1,y1,x2,y2):(c <':'&&c>48)
?x=x1,y=y1,*(c>'3'&&c<':' ?&y1: &t)
