This shows you how you can work with a Swing applications look and feel with color themes, custom button-shapes and watermarks using Kirill's Substance plug-in. You can use Substance with any Swing application you want: Substance lets you revamp the look and feel of your Swing application completely: Set up a color theme, customize the shape of buttons, or add a custom watermark in the background.

Watermarks
Watermarks are image files that are displayed in the background of your Swing application. In the case of NetBeans IDE, the watermark is painted over the background and under child components such as the Editor window. The background image will also shine through on panels, toolbars, menus, menu items and other UI components. Currently, the following predefined watermarks are available to choose from:

Stripes, Katakana, Bubbles, Mosaic, Binary, Latch, MetalWall, Crosshatch
Null, Image

The command line argument to specify one of these predefined watermarks is

-J-Dsubstancelaf.watermark=org.jvnet.substance.waterm ark.SubstanceKatakanaWatermark

Or

here is the coding sample - LayeredPane
