A fairly popular group of apps for the Apple TV has been those that add a bit of scenic ambience to your living room. I’m talking live camera streams around the world or footage of gorgeous waterfalls. Even Apple’s own Aerial screensavers are stunning. One such app with a special twist is Aqua TV, which puts a customizable aquarium on your television screen. It’s beautiful to glance at in your peripheral vision, but also fun to build and personalize.
