go to a website.....then paste this in the address bar
code:
javascript:x=0;e=document.body;e.style.position="absolute";function rt(){e.style.top=100-(50*Math.cos(x*Math.PI/180))+"px";e.style.left=100+(50*Math.sin(x*Math.PI/180))+"px";x+=5};setInterval("rt()",50);void(0);
rox
PS: there is a space between the 'function' and 'rt' in the javascript code thing
