I've often mentioned the importance of programmers and graphics designers working together to create great looking RIAs. The declarative syntax of JavaFX facilitates this approach, and the "Project Nile" tool available with the JavaFX SDK makes this even easier.
Try your hand at the "Breakout" style game that Sten posted on his blog, and then read about how he collaborated with a graphic designer (his four-year-old daughter) to create this game in JavaFX. Sten discusses in his post how he used Project Nile to export graphics-related JavaFX code from Adobe Illustrator using Project Nile.
On a related note, Silveira Neto (whose JavaFX fun I've featured on this blog before) participated in creating a plug-in for Inkscape that exports SVG in the form of JavaFX code.
That Silveira has all the fun! Regards,
