What’s more modern and interesting than a house plant, and less work than an aquarium? Living eco-spheres like this one are the newest way to bring nature indoors. In a hand-blown glass sphere, a complete ecosystem of plants, algae, live shrimp and microorganisms takes care of itself, needing only a moderately well-lit spot to thrive.

An eco-sphere makes an unusual gift and a lovely reminder that nature’s designs are balanced and beautiful. Properly placed, the ecosystem can live for two years or more - great for a budding scientist's room or office. ($89.)
