title: How to make this canvas effect, moving on the background
body: <p>In this site: <a href="http://shape.themeturn.com/html/dhome/index.html" rel="nofollow">http://shape.themeturn.com/html/dhome/index.html</a> you can see there is a Dot line effect which moves with the mouse. You will find it in the header section.</p>
  
  <p>I wanna know what are those effects called. I think they created it with HTML5 canvas (i, might be wrong!). How can i create such effect. And what skills are required??</p>
  
  <p>Thanks!</p>
