title: Detect when opacity changes
body: <p>Is there a way in <code>jquery</code> or javascript to detect when then opacity of an element changes then launch a function to add new effects like for example if you had a page where automatic things happen like an element faded in then you wanted to launch something else when that happened. How would you do this???</p>
  
  <p>It is kind of like a slide show.</p>
  
  <p>Here is a demo of what I have so far:</p>

  <p>Than I want when the last elements opacity changes then start the loop again</p>
  
  <p>Thanks in advance</p>
