title: iPad Safari-like zooming in and out thumbnails view
body: <p>First of all, I have plenty of experience on iOS development but I am not so keen on Core Animation. I would like to reproduce the effect in Safari (both iPhone and iPad) when the page you're viewing at shrinks itself and 'zooms out' into a thumbnail view, and after you select a given thumbnail, it then 'zooms in' and the corresponding page is restored.</p>
  
  <p>What is the best way to accomplish this? I would apply it to a reguiar UIView subclass - not a UIWebView - but I am not so sure on how to do the whole shrinking effect, and specifying the destination frame for the zoomed out thumbnail (suppose I have lots of thumbnails in the screen and I would like to position the current view into a particular thumbnail).</p>
  
  <p>Best,</p>
