Can you spot the differences?

Figure 1

Figure 2

I'll give you a clue, it is not the Look&Feel...



Give up? well it was kind of tricky anyway unless you see how each figure was created, let's see Figure 1 first:
import javafx.stage.*; import javafx.scene.*; import javafx.ext.swing.*; Stage { title: "FX" width: 100 height: 50 scene: Scene { content: { SwingButton { text: "Swing!" } } } }It turned out to be your run-of-the-mill JavaFX Script application, so what about Figure 2?
import griffon.builder.fx.FxBuilder new FxBuilder().stage(title: "FX", width: 100, height: 50) { scene { swingButton(text: "Swing!") } }Oh yeah... FX can be Groovy
