title: Canvas draw advanced circle with thorns on
body: <p>I know how to make circles and circle shapes with the mathematical PI, but I don't know what I am going to do if I want to make something like this:</p>
  
  <p><a href="http://imgur.com/jKh3nMq" rel="nofollow">http://imgur.com/jKh3nMq</a> (a circle with five thorns around on)</p>
  
  <pre><code>ctx.fillStyle = "red"
  ctx.beginPath()
  ctx.arc(0 + 50/2, 0 + 50/2, 50/1.75, 0, Math.PI*2, true)
  ctx.closePath()
  ctx.fill() // Gives me a circle, but how with thorns on?
  </code></pre>
  
  <p>I need help with drawing it, getting stuck, please help.</p>
