body: <p>I was visiting <a href="http://www.hottrixdownload.com/iphone/" rel="nofollow noreferrer">this website</a> with cool animated apps. I was wondering how's the easiest way of building a app like those. I almost bet it uses some kind of OpenGL ES.</p>
  
  <p>Is it a good case of <a href="http://cocos2d.org/" rel="nofollow noreferrer">cocos2d</a> usage?</p>
