Hi Seung-Ho,

   do for example in your script in the draw loop (example from hsimple.C):

     if (i && (i%kUPDATE) == 0) {
        if (i == kUPDATE) hpx->Draw();
        c1->Modified();
        c1->Update();
        sprintf(gif, "/tmp/gifs/pict_%.3d.gif", gifcnt++); // add
        c1->SaveAs(gif);                                   // add
        if (gSystem->ProcessEvents())
           break;
     }
  }

this will create a set of gif files. Now use a tool like 

http://www.lcdf.org/~eddietwo/gifsicle/

to make a single animated gif from these sequential gifs using:

gifsicle --delay=10 --loop *.gif > ../anim.gif

The result can be seen at:

Cheers, Fons.
