C is cool: OdeAanC of WriteInC 

#include <math.h> /*** ---- viznut --- http://www.hytti.uku.fi/~vheikkil/ */
main(v,i,z,n,u,t){for(v=-1;;)for(n=pow(/* gcc -lm sig.c; a.out > /dev/dsp */
1.06,"`cW`g[`cgcg[eYcb^bV^eW^be^bVecb^"[++v&31]+(v&64)/21),i=999;i;putchar(
128+((8191&u)>i?0:i/8)-((8191&(z+=n))*i-->>16)))u+=v&1?t/2:(t=v&6?t:n/4);}

(als je zo'n dingen leuk vindt, zie: http://ioccc.org/)

een fractaltje: 

main(k){float i,j,r,x,y=-16;while(puts(""),y++<15)
        for(x=0;x++<84;putchar(" .:-;!/>)|&IH%*#"[k&15]))
         for(i=k=r=0;j=r*r-i*i-2+x/25,i=2*r*i+y/10,
             j*j+i*i<11&&k++<111;r=j);}

#include <stdio.h>

main()
{
  for(;;)
      { 
          printf ("Hello World!\n");
      }
}
