How to create a custom loading screen in JavaFX?

I'd like to create a custom loading screen for a JavaFX application. Don't want the user to see the Java coffee cup icon, I want to put my own graphic there!

I've found out how to provide a static image, or even an animated GIF, but I'm more interested in a Flash-like screen where I can specify what the state of the image looks like at certain percentages.

Any ideas?

• If you're setting things up as shown on This blog entry, it looks like the answer would be 'no' - the loading graphic is just part of the overall options that are passed to the applet. Because this applet could be any java code (not just javaFX), there's no way to tie your custom renderer in.
