// <![CDATA[
var border=50; // how wide is each border
var effects=3; // how many of the effect are on the page
var speed=50; // how fast is the animation (lower is faster)
var colours=new Array("#9cf", "#c9f", "#fc9", "#f9c", "#cf9", "#9fc", "#6ff", "#f6f", "#ff6");
// above line lists colours for the groovy effect (can be as long or short as you like)
