During the opening keynote session Tuesday morning of JavaOne 2009, the first presenter showed a nifty Java app developed in JavaFX connected to a massive chat engine. The intent is to encourage people to network and collaborate during the conference. However it had some nifty effects baked in. During the session, they announced that by the end everyone will receive a link to download it. I’ll post some screenshots once I get it installed.

Update : It took a little longer than “by the end of the general session”, but eventually Sun sent out custom links for each attendee to use DarkChat. See images below.

(sorry I blurred some names here so this looks a little dodgy)

The chat app is exclusive to attendees at JavaOne, but demos JavaFX nicely. I believe they also stated during the general session that this is backed by the DarkStar web/gaming engine.
