Thanks Tommy,
Its mootools 1.2, IMHO the
best javascript library around.
You can find the full documentation for it here:
Simple Animated Menu for Mootools 1.2 -- consider: open blog | Web Design, Development and Marketing
If you are interested in playing with it, you can get the zip with a css file, a basic html template, the mootools js and the menu js here:

The menu code is dedicated to the public domain, so you can do whatever you want with it.
