title: Jquery resize image with a heart beat effect
body: <p>Hello want to make a image with a heartbeat effect.
  It has to resize a bit, let's say maximum 20 pixel bigger, and then goes to original size.
  It will be like a heartbeat, 2 beats - original, 2 beats - original.</p>
  
  <p>So far I found only this effect:</p>
  
  <pre><code>    (function pulse(back) {
      $('#seventyfive').animate(
          {
              'font-size': (back) ? '100px' : '140px',
              opacity: (back) ? 1 : 0.5
          }, 700, function(){pulse(!back)});
  })(false);
  </code></pre>
