actionscript 3 - How to Flash CS5 AS3 Random Elastic? -

i made photo gallery, every photo start come in with:

new tween(uiloader,"rotationx",elastic.easeout,90,0,4,true); 

and it's cool if photos come in same way, it's little bit tiered @ it. want ask here code make random fade, blinds, iris, fly, dissolve, squeeze, wipe, zoom, rotationx, elastic.easeout???? here code:

function completehandler(event:event):void {     uiloader.x =   (back.width - uiloader.content.width) >> 1;     uiloader.y =  (back.height - uiloader.content.height) >>  1;     new tween(uiloader,"rotationx",elastic.easeout,90,0,4,true); } 

something ?

var properties:array = ['rotationx', 'rotationy', 'rotationz', 'rotation']; var eases:array = [elastic.easein, elastic.easeinout,     elastic.easeout, bounce.easein, back.easeout];  function completehandler(event:event):void {      uiloader.x =   (back.width - uiloader.content.width) >> 1;     uiloader.y =  (back.height - uiloader.content.height) >>  1;     new tween(mc, getrandom(properties), getrandom(eases), 90, 0, 4, true); } function getrandom(array:array):* {     return array[math.floor(math.random() * array.length)]; } 

edit :
