title: Javascript & Canvas: Endless random animation of slightly morphing circle?
body: <p>I'm completely new to <code>canvas</code> and animating objects with it. I did a little bit of research (e.g. I found <a href="http://raphaeljs.com/animation.html" rel="nofollow noreferrer">RaphaelJS</a>) however I couldn't find any general answer or tutorial on how to create a "morphing" circle.</p>

  <p>The image I posted here is what I would like to do:
  I'd like to create <code>one</code> circle that is <code>endlessly</code> animated via a <code>randomizer</code> and is slightly morphing its contours.</p>
  
  <p>I know this might be not a "real" question for this forum, however I just wonder if anyone could provide a few tipps or tricks on how to do something like that.</p>
  
  <p>By "how to do something like that" I'm speaking actually about the technique on how to morph a circle. Do I have to "mathematically" create a circle with dozens of anchor-points along the edge that are influenced by a randomized function?</p>
  
  <p>I would really appreciate some starting help with this.</p>
  
  <p>Thank you in advance.</p>
