Based on some of the posts in the forum, I went to Nova's website. I saw, from one of the images on their website, that Marine Aquarium 3.0 will display on at least 3 monitors, each with a distinct background. How does this work on a single 17" (laptop), or 20" (desktop) monitor? Do you just get one of the backgrounds, does the background scroll as the fish swim, or do you select the background you prefer?
