JGoodies look & feel:JGoodies look&feels让你的Swing应用程序与applets看起来更漂亮.屏幕截图如下:

Compiere Looks:Compiere Looks是一个3D color，它扩展了Java Metal pluggable Look and Feel。

Liquid look & feel:The goal of this project is to provide a look and feel based on the Mosfet Liquid KDE 3.x theme.

Tonic Look & Feel:这是Swing金属(Metal)外观的免费实现方案．

Squareness:Squareness的目的是为不同应用程序和操作系统提供一个统一的外观。

LipstikLF:LipstikLF Look and Feel是模仿KDE主题引擎Lipstik实现的一个Swing皮肤。LipstikLF设计地非常快速、简洁并尽可能做得与Lipstik外观相似。它适用于Java1.4和1.5。

Napkin look & feel:The Napkin Look & Feel is a pluggable Java look and feel that looks like it was scrawled on a napkin. You can use it to make provisional work actually look provisional, or just for fun. The idea is to try to develop a look and feel that can be used in Java applications that looks informal and provisional, yet be fully functional for development. Often when people see a GUI mock-up, or a complete GUI without full functionality, they assume that the code behind it is working. While this can be used to sleazy advantage, it can also convince people who ought to know better (like your managers) that you are already done when you have just barely begun, or when only parts are complete. No matter how much you speak to their rational side, the emotional response still says "Done!". Which after a while leads to a later question: "That was done months ago! What are they doing? Playing Quake?" A good article on this is Joel on Software's “The Iceberg Secret, Revealed”. So the idea is to create a complete look and feel that can be used while the thing is not done which will convey an emotional message to match the rational one. As pieces of the work are done, the GUI for those pieces can be switched to use the "formal" (final) look and feel, allowing someone looking at demos over time to see the progress of the entire system reflected in the expression of the GUI. Over time, several folks have just liked the thing and wanted to use it for non-provisional GUI's. Sometimes this is because the application itself seems to match the theme, such as a brainstorming tool. And sometimes it's just that it looks fun. This is all done using the Java Swing pluggable Look & Feel framework.

GTK/Swing:GTK/Swing是一个可插入的Swing外观.它尽可能地模仿并接近默认的GTK+.

A03 Look And Feel:这个Java Look&Feel整合了常用到的一些外观风格。

Oyoaha look & feel:Oyoaha look & feel现在也是一个开源的项目.它基于apache-like license发布.
