title: Move an image according to the mouse cordinates using jquery
body: <p>I am trying to develop a HTML5 white board. I want the users viewing the board 
  to know where exactly the presenter is pointing within the screen. I am able to 
  collect the mouse movements using <a href="http://api.jquery.com/mousemove/" rel="nofollow">this jquery function.</a> </p>
  
  <p>But even if i succeed to pass this values
  to other clients using php, how can I emulate it? <strong>Is it possible to move a small 
  pointer image, based on the co-ordinates obtained from the presenter?</strong></p>
  
  <ol>
  <li>Is there any functions or snippets from which I cant get started?</li>
  <li>Will this be very hardware intensive task that normal people may
  have issue? </li>
  <li>Is this the best way to achieve what I am trying to achieve?</li>
  </ol>
