Install JavaFX Application …From Apple's Mac App Store
Probably the first JavaFX / Java application called "Ensemble" is available directly from the Mac App Store.
[The application was taken from the store to fix some glitches, but it should come back soon]
Tip: if you are a developer, there are easier ways to get the Ensemple running on your Mac :-)
