Nice 
Here are available 5 styles of Aqua Nodes Preloader for you.
It’s really easy to change effects, color and size. I commented very carefully, so you absolutely change parameters and create new styles on your own.
Morever, they’re almost small size 
Usage:
// stop the movie from continuing
stop();
// create a function called onEnterFrame
// to stop the Preloader when preloading process is done.
onEnterFrame = function(){
// the movie is completely loaded when
// the reference attribute "isDone" of Preloader MC set "done".
if (mPreloader.isDone == "done"){
// delete the onEnterFrame event handler
// so that it is no longer being called
// every frame
delete onEnterFrame;
// tell the main timeline to play
play();
}
}
Hope you enjoy, guys.
