Now, you can see my slide at http://servletgarden-point.appspot.com/slideshow. As the url shows, my slide itself was a demo built on Google App Engine using JRuby on Rails. This app uses jQuery UI and ajax. Click on buttons on the left side, then right side contents will change, and you'll see accordion. Also, you can try examples I showed in my presentation. Cloning the git repo,
and look at README to run examples.
