Is there a plugin for textarea of thread or comment to open a wide textarea?

Here what I mean, let's base it on facebook:
When the user click edit, the textarea will be default size like this


When the user is editing his post/comment, the textarea will open wide depending on the text inside the textarea, like this

Use jQuery, (GOOGLE my friend)

Something like,

$('textarea').focus(function () {
    $(this).animate({ height: "4em" }, 500);
});

Or even:

$('textarea').focus(function () {
     $( this ).css({
        "height": "100px",
        "width": "200px"
     });
});
