From the developers description:
"She was the biggest and the most luxurious liner of her time. But the maiden voyage of the “ship of dreams” ended as a nightmare. Dive into the depths of the Atlantic and explore the mysterious world of the Titanic imbued with the spirit of the past.
See flashbacks of this beautiful vessel sailing across the ocean. This truly realistic setting will bring memories of the Titanic back to life. The story lives on…"
Little Bears Commentary : I guess some people like screen savers however I feel its an insult that people need a screen saver to tell a sad event... If you really want to know the real story behind the Titanic, you might be more entertained picking up the book, reading it, or watching the movie.
