Fairy is a stand-alone (no dependencies) JavaScript class for generating fairy-like pulsating thingies. It's almost entirely pointless... but very fun. It's best when used as a bookmarklet.
The code is quite simple so I'm not going to litter this sacred ground with documentation.
I'll just leave this here:
fairyEnvironment.spawn(25, function(){
if (this.dom) {
document.body.appendChild(this.dom);
this.start();
}
});
// Now you have 25 fairies flying around!
