msg=msg.split(''),amount=msg.length,Y=0,X=0,ypos=0,xpos=0,ybase=new Array(),xbase=new Array();
angle = new Array(),divTop= new Array(),divLeft=new Array();
DocHeight=(document.layers)?window.innerHeight:window.document.body.offsetHeight;
DocWidth=(document.layers)?window.innerWidth:window.document.body.offsetWidth;

//initial layer placement!
for (i=0; i < amount; i++){
divTop[i]=Math.round(Math.random()*DocHeight);
divLeft[i]=Math.round(Math.random()*DocWidth);
}
if (ns){
for (i = 0; i < amount; i++)
{document.write('<layer name=nsd'+i+' top=0 left=0
