When you combine some neat functionality courtesy of PHP with the cleverness of jQuery you can produce some pretty cool results. NETTUTS has published a tutorial (Creating a Dynamic Poll with jQuery and PHP) for creating a poll using PHP and XHTML, then make use of some jQuery Ajax effects to eliminate the need for a page refresh, and to give it a nice little bit of animation.
