Another module that is quite interesting that you may use in the Featured Products block is available at http://www.ecartservice.net/03082009/moving-boxes-home-featured-jquery-module/
This module is also based on
jQuery and features the products
in moving boxes.
The moving box interacts with the click of the arrow button on the sides. It will show the next featured product once you click this arrow (previous and next are converted into red arrow buttons).
It can replace your default theme, which displays four featured items in the featured blocks in the center column. This moving box enhances the interactivity and looks quite cool too.
