This is an example of the menu I have been using on my site at pupius.co.uk. It was never meant for general release so the code is quite messy and inflexible in what can be done with it. All changes to the appearance should be made in the menu.css and one change to the constant MENU_TOP_OFFSET in the pupius.co.uk-menu.js script.
