PHP AJAX based instant star rating script

If you find it hard to add your own starrating script into your pages, then this is for you.

The starrater comes with everything you need to implement a star-rating element into your system in no time. It’s based on PHP and AJAX ( mootools ), so everything is automated for you. You only need to include one line of code per rater ( multiple on one page possible of course ).
Benefits:

Adds a lock on each IP for a certain rating element, so anyone with the same IP can only vote once.
Automatically inserts votes into the db, calculates the average and displays that on the starrater as initial value.
No need to program your own logic for the starrater
Tooltip with ajax effects
