I'd love to add a blinking effect like this, but I think `setInterval` is overkill for what's mere cosmetic stuff:

```js
jQuery(function(){
  $("#watch").each(function(){
    var $box = $(this);
    var show = true;
    setInterval(function(){
      var m = moment();
      $box.text(show ? m.format('H:mm') : m.format('H mm'));
      show = !show;
    }, 500);
  });
});
```

```html
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src='//cdnjs.cloudflare.com/ajax/libs/moment.js/2.9.0/moment.min.js'></script>
<div id="watch">--:--</div>
```

Is there a newer JavaScript API I could be using, or maybe a CSS transition?
