simple as:

$("a").jEffects('bubbles');

flexible as:

$("li").jEffects({ 
	type : 'fireball',
	colors : [ '#f77', '#7f7', '#77f'],
	chaos : 100,
	chars : ['a', 'b', 'c'],
	targetX : 200,
	targetY : -100,
	particles : 8,
	duration : 1000, 
	randomizeParticles : true
});

complex as:

$("div").jEffects([
	{ type:'bubbles' },
	{ type:'snow' },
	{ type:'fireball', targetX:  300 },
	{ type:'fireball', targetX: -300 }
]);

beautiful as:

$("#anything").jEffects(

	/* Your imagination goes here */

);
