Simply XPMC Induztry

Simply XPMC Induztry is a skin for the Trillian instant messenger, which adopts dark and light grey tones to customize the look of this application. Inspired by an old visual style for Microsoft's operating system, this skin resembles Windows XP. Although it's an old skin, it can still be installed on the latest editions of Trillian, whether you have a free or pro account.

The downloaded package includes a preview, so you can check it out before deciding whether or not you want to install the skin. To do this, extract the files from the downloaded archive, make sure to place them in a folder, then move that folder to the Skins folder of Trillian's installed directory. If the instant messenger was already running before doing this, it's necessary to restart it to be able to apply the new skin.

To select it, open the Trillian menu, select Preferences, find the Customization area on the bottom of this window, then click Skins and choose Simply XPMC Induztry from the menu. It modifies the style of the main app window as well as popup menus.

As the developer explains in the settings file, you can go ahead and change the configuration to experiment with different colors that you like more. Just make sure to create a backup of the skin's files to go back to the original settings.
