We always said that, if we became super villains, we would get a giant fish tank to put in our office so our enemies would know we meant business. We're tweaking that little now and opting for one of these "high definition" aquariums. These aquariums have no top and the water runs down the sides of the glass into hidden drains. From there it's recirculated back into the tank. The result is a glass-like sheet of water on the outside of your tank that makes everything inside look incredible. It's also quiet, energy efficient and a heck of a lot cooler than that old 2-liter bottle you've been keeping your fish in. $1,299 and up.
