I tried John Resig's processing.js, which is processing implementation on javascript.

This is a program to draw the Sierpinski carpet fractal.

var max = 3;
void draw_iter(x,y,w,h,n){
   var wn = w/3;
   var hn = h/3;
   pushMatrix();
   translate(x,y);
   rect(wn,hn,wn,hn);
   popMatrix();
   if( max <= ++n ) return;
   for( var i = 0; i < 9; i++ ){
      if( i == 4 ) continue;
      draw_iter( x+wn*(i%3), y+hn*Math.floor(i/3), wn, hn, n );
   }
}

void setup(){
   size(144,144);
   background(120);
   stroke(255);
   draw_iter(0,0,144,144,0);
}

As you see, it's quite simple. You can see the output picture  of this program in my another blog
