A desktop theme is a convenient way of converting several aspects of the desktop environment at the same time. Desktop themes are usually based on some specific topic, e. g. a movie, a band or a game. There are thousands of themes available on the web, ranging from top quality professional creations to amateurish crap.
Themes are almost without exception stored in zip format.

All elements can be previewed or auditioned. When you've built a new theme, you can save it for later use on your system or share it with others.
