title: Zoom-through Transition Effect
body: <p>A bunch of sites, such as <a href="http://scaleofuniverse.com/" rel="nofollow">http://scaleofuniverse.com/</a>, have zoomable interfaces that will allow you to "zoom through" items to reveal "smaller" items contained within them. I have always seen this done in Flash, but am wondering how it could be made using JavaScript and CSS. Is there any open-source library out there that supports this feature?</p>
  
  <p>Also, I have had a look at impress.js, which has some very cool features, but I am unsure whether I would be able to accomplish the desired effect using this library. Is it just a matter of using the right CSS styles?</p>
