  <p>Link to my code on Glitch <a href="https://glitch.com/~thin-newsstand" rel="nofollow noreferrer">https://glitch.com/~thin-newsstand</a></p>
  
  <p>Working explained.
   1. Save camera button saves the rotation into select along with the scene and 
    custom data attribute name data-r
   2. If you inspect select dropdown options, you will notice.
   3. When select option is changed, it will change sky image from select option and also change rotation.
   4. I have used aframe-viewable-component.js to restrict top/bottom movement of skybox.</p>
