I setup a quick demo page showing how to use a combination of many things I have wrote about on my blog. Take a look if you want to see how easily you can do some cool things with YUI (update – and jquery).

update 5/08/09 - I change some of the javascript from yui to jquery. I converted the old YUI carousel to Jcarousel.(http://sorgalla.com/projects/jcarousel/)
