title: HTML5 Canvas (or alternative): Moving lines to simulate meridians on a planet
body: <p>This is my firs excursion on the HTML5 canvas, I have working knowledge of jQuery and Javascript.
  I'm trying to create a "spinning globe" effect with it.
  The idea is to have a circle and meridians "spinning" on it, to give the effect of a rotating globe.</p>
  
  <p>I've drawn the circle and now I'm trying to create lines that start from the right (following the curve of the circle), move towards the centre straightnening up (in the middle they are straight) and follow the inverse curvature on the left, ending with the circle.</p>
  
  <p>I'm trying to do this with the HTML5 canvas and jQuery but I'm not sure of where to start... should I create an arc and then try to animate it?</p>
  
  <p>I'm even wondering if the canvas is the right tool or if I should use anything else.</p>
  
  <p>Any suggestion is welcome!</p>
