Great little snippet to place ids in Drupal menus. Now you can style each one for a little graphic priority.

Great jquery script for rendering a menu of rss feeds to choose from.

This modules plus a few others (listed on the page) allow you to create a slick menu for browsing hierarchical taxonomies in Drupal. Not quite Hulu filtering, but still great.

A brilliant way to animate a navigation menu.

Check out the menu roll over. Very clean. Font reminds me of the Zune.
