Can I customize output?

Yes, you can overwrite default css style. The XHTML/CSS layout is:

<div class="wp-blogbabel">
    <!-- 'labssaidmade' is a blogbabel slug example -->
    <div class="topten">
        <a href="http://it.blogbabel.com/classifica-blog/blog/labssaidmade" target="_blank"><span>BlogBabel</span></a>
    </div>
    <div class="url">
        <a href="http://labs.saidmade.com/" target="_blank"><span>labs.saidmade</span></a>
    </div>
    <div class="rank">
        <span class="label">Rank:</span><span class="down">3603</span>
    </div>
   <!--
       class 'down' when trend is down, ese 'up' or 'static'
       see below for css define
   -->
    <div class="trend down"/>
        <div class="credits">
             <a href="http://wordpress.org/extend/plugins/wp-blogbabel/" target="_blank">Powered by WP BlogBabel</a>
        </div>
    </div>

In the Plugin directory CSS you can see a default standard style-sheet:

/*
 * Main container
 */
div.wp-blogbabel {
    display:block;
    width:100px;
    height:100px;
    background:#eee;
    border:1px solid #aaa;
    -moz-border-radius:8px;
    -webkit-border-radius:8px;
    font-family:Arial;
    line-height:24px;
}

/*
 * Use this setting for all links
 */
 div.wp-blogbabel a {
     text-decoration:none;
 }

/*
 * TopTen is a link to BlogBabel sheet
 */
div.wp-blogbabel div.topten {
    text-align:center;
}
div.wp-blogbabel div.topten a {
    background:#ccc;
    -moz-border-radius:12px;
    -webkit-border-radius:12px;
    font-size:10px;
    margin:4px 4px 0;
    display:block;
    border:1px solid #aaa;
    line-height:14px;

div.wp-blogbabel div.topten a span {}

}
div.wp-blogbabel div.rank span.label {
    display:none;

 div.wp-blogbabel div.rank span.up {
     color:#0f0;

 div.wp-blogbabel div.rank span.down {

 div.wp-blogbabel div.rank span.static {
