Scott Kovatch announced yesterday that the Ensemble JavaFX demo app is back up on the Mac App store. If you are not familiar with it, Ensemble includes demos of pretty much everything JavaFX has to offer.
So if you have a Mac, here is the link to it on the Mac App store.
To add to the fun, James Gosling thinks this is pretty cool.
What does this mean for Java developers? That you too will be able to publish your JavaFX applications on the Mac App store. If my memory serves me correctly from the JavaOne presentation, Mac packaging of Java will be included in the next even numbered point release. You should be able to test it out with the early access version right now.
