Kaleidoscope is the ultimate program for enhancing (well, at least changing) the appearance of your Mac s GUI, etting you switch between completely different interface designs provided by plug-in modules called Schemes . Change the style and colors of your windows, system text, menus, and more. Kaleidoscope also comes with several schemes loosely based on the shapes and layout of standard Apple platinum interface, but with creative new colors. Or for a more conventional interface, Kaleidoscope can make your Mac look like it is running a different operating system, or even another version of the Mac OS. In addition, there are several third-party schemes available (check the Kaleidoscope home page). For more detailed information, including on updates, please read the documentation or visit the home page.
