Well it's finally ready enough to go live so now I can plug the big jQuery-driven project I've been working on. It's called IT Assistant and is intended to make shopping to IT equipment easier (and more fun from the comments I've had back on it so far :) ).
http://www.pcwb.com/assistants/ the product selector page is almost entirely jQuery driven. The follow up pages (accessories, upgrades, etc) are server-side based but they do make use of Thickbox for displaying Flash movies.
