And the "| head", which was probably there just to make a point
without having to watch 1000 lines, and replace the "printf" with
seq's "-f" flag:

 for i in `seq -f "%04g" 1 999`; do
  composse -compose atop bubbles.png 0*.png image$i.png
 done

I'm not sure that the "0*.png" argument is what you want either.
