While it may look like the above living room has a TV showing an aquarium screen saver mounted on the wall, that's not accurate. No, that's a real aquarium, mounted in the wall to make it look like a TV. Awesome.
Aquavista is a company that makes "panoramic wall aquariums," which is a fancy way of saying the cram an aquarium into your wall. And they look pretty slick! There are nice features such as a programable LCD touchscreen panel to control all of the essential functions of the tank, and it comes with all the proper fixins to keep your fish from getting flushed. Plus, it won't rot your brain like a real TV.
