Serialize animations in jQuery

var anim = {
        // Temporary cue of animations 
	anims : [],
        
        // Stored cue of animations for looping
	store: [],

        // Register a temporary animation
	register : function(obj, anim, dur, out) {
		this.anims.push([obj, anim, dur, out]);
	},

        // Start the animations. When an animation is done it gets 
        // erased from the temporary cue.
	start : function() {
		if(this.anims.length != 0) {
			var cur = this.anims.shift();
			var that = this;
			var once = true;
			$(cur[0]).animate(cur[1], cur[2], function() {
				if(once) {
					setTimeout(function() { that.start() }, cur[3]); 
					once = false; 
				}
			}); 
		} else {
			this.refresh();
		}
	},

        // Comes back to the original form and starts looping.
	refresh : function() {
	  this.anims = this.store.slice(0);
	  this.start();
	},

        // Save the current cue.
	save : function() {
		this.store =  this.anims.slice(0);
	}
}
/*
** Usage:
anim.register('#slide-1', {opacity:1, width:100, height:200}, 2000, 200);
anim.register('#slide-2', {opacity:1, width:10, height:20}, 2000, 200);
anim.save(); // this is for looping
anim.start(); // start animation
