title: HTML5 Animating a dashed line
body: <p>Being relatively new to the HTML5 game, just wanted to ask if anyone knew if it was possible to animate a dashed line along a path? Think snake from Nokia days, just with a dashed line...</p>
  
  <p>I've got a dashed line (which represents electrical current flow), which I'd like to animate as 'moving' to show that current is flowing to something.</p>
  
  <p>Thanks to Rod's answer on <a href="https://stackoverflow.com/questions/4576724/dotted-stroke-in-canvas">this</a> post, I've got the dashed line going, but am not sure where to start to get it moving. Anyone know where to begin?</p>
  
  <p>Thanks!</p>
