title: Rotate SCNNode infinitely 360°
body: <p>I'm looking for a way to rotate a note 360 degrees around its z-axis. The node holding the camera moves negatively along the z-axis and is not allowed to change its y &amp; z.
  I've already tried a <code>CABasicAnimation</code>, but without success.</p>
  
  <p>Can anyone point me to a solution?</p>
