Christmas advent calendar
<p>I have a vision of an advent calendar, where there are pictures of real windows with shudders, and when the user clicks on a picture, the shudders open to reveal what's behind them.</p>

<p>How can I do this?  I suppose I could use the primitive slideDown method in jQuery.  But is there a slideLeft and slideRight?  Or an openDoor, where each shudder rotates on an axis?</p>

<p>This would be one div that has a transition of opening to both the left and right at the same time.</p>
