Even though this next device isn't really a gadget, per se, as you cannot take it home with you, I could easily make a home out of this.

As it turns out, some hotel in Berlin, the Radisson SAS Hotel to be exact, has created the largest fish tank in the world at 80 feet tall and 260,000 gallons of water. Here's another impressive number: it has 56 species of fish with over 2,500 individual fish altogether.

If you want, the hotel offers an elevator view in the middle of it. That, or you can pay $375 for the ultimate room with an underwater view.
