title: What do you call a looping progress bar?
body: <p>Ok I'm just at a loss for what the correct terminology is for this.  I'm looking for the correct name to call a progress bar that "loops".  Instead of the standard progress bar that fills up from left to right to 100%, this looks exactly like the progress bar but a small portion of the fill color constantly loops, never filling the whole progress bar to 100%, basically making it an eternal progress bar similar to a <a href="http://www.ajaxload.info/" rel="noreferrer">Ajax loading image</a>.  Microsoft likes to use this progress bar in their dialogs now.</p>
  
  <p>What do you call this thing so I can search for some controls, etc.?  Does .Net have a control for this?</p>
  
  <p>Thanks</p>
