title: Weather HD animation
body: <p><br />
  I just want to know how is the animation done in the Weather HD App:

  <p>Is it done by Images, Videos, actually animation or a mixture of all. <br />
  To me it looks like that (mix) and how to actually implement it. I just want to get an idea of how to do something similar. </p>
  
  <p>Thanks</p>
