title: JavaScript shrinking/growing circle transition
body: <p>My first question here. :)</p>
  
  <p>I'm looking for a transitions between two images where the image first shrinks in a circle shape and then the circle grows again containing the other image. It's hard to explain, and I may be using the wrong words, because I can't find anything about it on the Interwebz. </p>
  
  <p>I'm talking about an effect like the Loony Toons ending.

  <p>That shrinking-to-black, can it be done in JavaScript/JQuery?</p>
