Web 3.5 Arrival or Swing Apps Rocks With Java 6 Update 10 - an 3D, Flickr, WebStart App
Not only applets are interesting again. The load and start of aerith takes about 10 seconds on my machine with Java 6 update 10. You will need to have a flickr account to tests it. If you do not have one - just type in "romainguy". The application is really amazing - especially the slide show.
