Andy-Poll

Andy-Poll is an easy to install poll-script, written in php. It uses Ajax, so if a user votes, the results are updated without the need of reloading the page. Moreover, the results are updated dynamically every 10 seconds for all visitors without reloading the page. The polls can be easily created with an admin-tool. The script is template-based, so it can easily be changed to your desired design. You can see the script in action on the author's page.
