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.

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?

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