If you feel like publicizing your programming prowess and you missed the JavaFX developer challenge, you should take a look at the WidgetFX contest.

WidgetFX is a container for desktop widgets written in JavaFX and is itself written all in JavaFX. And is already filling up with a number of useful widgets. From the obligatory clocks, calendars, post-it notes, to news readers, mailers, bookmark holders and twitter clients.

Or you might just like to put them all on your desktop.
