However, I was disappointed when I clicked the Settings button in the Screen Saver Settings dialog box ( Figure A) and encountered the message shown in Figure B that the screen saver lacks customizable options. So when I began experimenting with Windows Vista, I was excited about the new batch of screen savers: Aurora, Bubbles, Ribbons, Windows Energy, Windows Logo, and a revamped version of an old standard, Mystify. If you wanted additional screen savers, you had to purchase the Plus! packs. I had always hoped that Microsoft would add other OpenGL screen savers in subsequent versions of Windows, but they never did the same OpenGL screen savers appeared in every version of Windows after that point. Not only did this screen saver provide truly spectacular graphics due to the powerful nature of the OpenGL technology, it also offered multiple configuration settings with which to customize the display. At that time, my favorite screen saver quickly became 3D Pipes. As you may recall, Microsoft first introduced OpenGL screen savers in Windows NT 3.x.
