Assigning multiple values, or an array to the flapper

[jantsdesign]

I have the code below which has 2 fields, a year with 4 characters and a position with 2 characters.
It's working so far and currently 'flaps' to show 2014 02 then clears the letters and then re-flaps to show 2014 02.

How would you go about assigning multiple values to this script so I could 'flap' from 2014 02 to 2013 01 to 2012 04 etc...

var $demos = $('#animation_demo input');
setTimeout(function(){
$year.val('2014').change();
$position.val('02').change();
var toggle = true;
setInterval(function(){
if (toggle) {
$year.val('2014').change();
$position.val('02').change();
}
else {
$year.val('').change();
$position.val('').change();
}
toggle = !toggle;
}, 3000);

            }, 1000);
