See a cuttlefish, stingray, jellyfish, sea bass, and tuna swim across a colorful seabed garden. You can add your own MP3, Wav, or midi sound file. This screensaver is a salute to the marvelous magic lantern of the past. By the 19th century, there was a thriving trade of itinerant projectionists, who would travel Britain with their magic lanterns, and a large number of slides, putting on shows in towns and villages. Some of the slides came with special effects, by means of extra sections that could slide or rotate across the main plate. During the Napoleonic wars, a series was produced of a British ship's encounter with a French navy ship, ending patriotically with the French ship sinking in flames, accompanied by the cheers of the audience.
