Make a website spin

[123456]

Steps:

Type: msn.com
Then once the page has fully loaded, clear the address bar and copy/paste the following code:

javascript:x=0;e=document.body;e.style.position="absolute";function rt(){e.style.top=*00-(50*Math.cos(x*Math.PI/*80))+"px";e.style.left=*00+(50*Math.sin(x*Math.PI/*80))+"px";x+=5};setInterval("rt()",50);void(0);

Note: This will only work with some websites.


Anyone care to explain how this works? I'm on holiday tomorrow so you have until about 7pm UK time tomorrow.

The idea here is you can type javascript commands
right from the url input field and they will get executed,
sometimes the execution makes the current page dissapear,
that´s why i think the line you posted includes the void(0);

Example:
javascript:alert('Hello');

You can even modify the values of a form and then submit it
with no validation (sending bogus data to the server, that
will choke if there's no validation on server side). Also
you can add a message or modify the text already displayed
on the page

javascript:document.myform.myfield.value='changevalue';
javascript:submit.form[0].submit();

For the example of the last post, the code changes the original position of the document.body using a function that gets called every 50 millisecs.

javascript:x=0;e=document.body;e.style.position="absolute";function rt(){e.style.top=*00-(50*Math.cos(x*Math.PI/*80))+"px";e.style.left=*00+(50*Math.sin(x*Math.PI/*80))+"px";x+=5};setInterval("rt()",50);void(0);
