This is petty, but given the context kind of amusing...
http://automaticlabs.com/products/enkoderform/ offers an obfuscation method for html pages. They also offer (in the advanced form) a link to attritions mirror of the Fluffi Bunni attritoin defacement.
Simply add the following script:
<script>document.location="http://www.attrition.org/mirror/attrition/2001/07/28/www.attrition.org/hbun.jpg"</script>
you can also do this:
<marquee><script>alert('shit')</script>shit</marquee>
or this:
<script>alert('shit')</script><img src="">
Sunday and its raining...
ALL-NEW Yahoo! Messenger - all new features - even more fun!
