Dream Aquarium - screen saver in the form of a realistic virtual aquarium. The user is given the opportunity to peacefully observe the life of aquarium fish, so realistic that it is difficult to believe. The fishes behave like living ones - they move their fins, eyes and mouth, crab crawls along the bottom, algae move with a degree of swinging. It is possible to set up aerators, feed underwater inhabitants in automatic or manual mode. It is possible to use the screen saver on several monitors at once. It is possible to "inhabit" an aquarium of more than a hundred fish of 23 different species.
