here is an interesting demo. note josh's comment:
One thing I've noticed when building my demos is my development style. It's totally different than when writing Java programs. When I code Java, I think first about the objects and interfaces, create empty .java files, and then start writing the implementation. When I write JavaFX script using the preview mode in NetBeans my style is completely different. I immediately start throwing up shapes and UI components, constantly moving code around and renaming things. Once I have something solid only then do I split it into separate classes. It's definitely a less rigorous but more fluid development experience. And, dare I say it, more fun!
javafx seems like a cool little thing. i'm not sure how useful it really is. it maybe worth checking out for a quick and dirty hackystat ui. maybe its something we can use for a client side telemetry wall viewer.
anyway... just an idea.
