    <script type="text/javascript" src="js/jgames/jquery.jgames.js"></script>
    <link href="js/jgames/css/style.css" rel="stylesheet" type="text/css" />

        var board_chess = [
            ["br", "bn", "bb", "bk", "bq", "bb", "bn", "br"],
            ["bp", "bp", "bp", "bp", "bp", "bp", "bp", "bp"],
            [" ", " ", " ", " ", " ", " ", " ", " "],
            [" ", " ", " ", " ", " ", " ", " ", " "],
            [" ", " ", " ", " ", " ", " ", " ", " "],
            [" ", " ", " ", " ", " ", " ", " ", " "],
            ["wp", "wp", "wp", "wp", "wp", "wp", "wp", "wp"],
            ["wr", "wn", "wb", "wk", "wq", "wb", "wn", "wr"]];
       $("#chess").chess(board_chess);

Creating an Animation
Creating an animation is very easy. You simply pass an array of states, and the time interval between states (in milliseconds) to the chessAnimator() function. Below is the code to render the above right Chess animation.
