Infinity pools have been around for a while, so it only makes sense someone would apply the same idea to another home-sized water feature: the aquarium. ZeroEdge Aquariums ($600 and up) do exactly that, providing overflowing aquatic environments for all types of fish and sea creatures in a variety of styles and shapes, ensuring you can find one that’s right for your home or office. Just remember: no edge equals no lid, so be sure to keep the Darla-types away. [Thanks, Brian]
