                // I want the box go to the position like translateX(0) 
// and then back again to translateX(114%) without hardcoding the 114% in JS

	.to("#box-1", 2, { x: function() {
		return "+="+ $("#box-1").width();	
	}, width: 0 })
	// I'd love to do something like this:
	.to("#box-1", 2, function() {
		// some calculations...
		var width = $("#box-1").width();
		var someOtherCalculation = 0; // imagine fancy math here
		var bg = (some_fancy_if) ? "green" : "red";
		return { x: width, width: someOtherCalculation, backgroundColor: bg }

	// with the additional parentheses the timing of the .add() is no longer ignored
	// but the width calculation fails totally, seems to be 0? Why?
