I've done it but I'm not hapyy with it, it only works in IE and I don't know why. Can some one please tell me why?
Here's the code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title>Untitled Document</title>
<script type="text/javascript">
function doIt() {
text_which_scrolls = document.getElementById('wee').innerHTML
new_text=""
i= new Number(0)
while (i<text_which_scrolls.length)
	{
	new_text += text_which_scrolls.substring(i,parseInt(i)+60)+"*"
	i=i+60
	}
alert(new_text)
document.getElementById('wee').innerHTML = new_text
}
</script>
</head>

<body onload="doIt()">
<textarea cols="20" rows="10" id="wee">
