Tool to graphically customize the Nimbus look and feel

I am looking for a tool that I used a few months ago, but I am not able to remember the name.

This is a graphical tool for customizing the Nimbus Swing look and feel. On the right sid开发者_JAVA百科e of the window, there was a set of sample Swing components, and on the left the list of all customizable properties (the same than the result of UIManager.getDefaults()). The tool allows to change the values of the properties (color, font, integer values), and to see the result on the right side in real time.

The tool allows to export the changes in a file, too (the java code that sets the customized values).

I remember that the whole program was only one big java file. And I think this tool was part of another project (the tool is standalone, though).

I just found it. The name of the tool is NimbusThemeCreator, and it is part of the project Aephyr.
