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.

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.
