Here are 2 C-programs that generate the Mandelbrot set in ASCII! The basicly 
do the same thing, but with different outputs! If you are a coder, you can 
change the code to generate other pictures..... Enjoy!



Program #1
------cut here-----------
main() { int x,y,k; char *b=" .:,;!/>)|&IH%*#@";double cr,ci,zr,zi,temp,cx,cy;
for (y=30;puts(""),cy=y*0.1-1.5,y-->=0;){for(x=0;cx=x*0.04-2,zr=0,zi=0,x++<75;){
for(cr=cx,ci=cy,k=0;temp=zr*zr-zi*zi+cr,zi=2*zr*zi+ci,zr=temp,k<112;k++)
if(zr*zr+zi*zi>10)break;printf("%c",b[k%16]);}}}
------cut here-----------



Program #2
------cut here-----------
float o=0.075,h=1.5,T,r,O,l,I;int _,L=80,s=3200;main(){for(;s%L||
(h-=o,T= -2),s;4 -(r=O*O)<(l=I*I)|++ _==L&&write(1,(--s%L?_<L?--_
%6:6:7)+".:,;!/>)|&IH%*#@",1)&&(O=I=l=_=r=0,T+=o /2))O=I*2*O+h,I=l+T-r;}
------cut here-----------
