Signature GS is a collection of Control Panels that make your Apple IIGS easier and more fun to use by adding a Screen Blanker, a Desktop Pattern Editor, a Sound Selector, and a Boot Setup Utility to GS/OS version 5.0 or later. Features: Phantasm ? Gives your screen something to do through a variety of fun, attractive screen activities, including ""Magic Molecules"" and ""Slimy Slugs."" Graffiti ? There's nothing wrong with the IIGS desktop, except it's boring. Graffiti gives you a variety of colorful desktop patterns to choose from, or you can create your own with the built-in desktop painter. Sonics ? Customize your IIGS sounds, and assign special sounds for specific functions. And these aren't just beeps ? they're fun and entertaining. Boot Master ? Changing the configuration of all your IIGS drivers, and system components can be a pain. Boot Master makes it easy by putting all the controls for your IIGS drivers on one master control panel.
