We cannot tell a lie: we first saw these in a kid-free apartment, being used as ....er...mood lighting. But to us, they looked like the perfect mood lighting for a nursery. Aquapict LED Jellyfish are a trio of faux jellyfish, floating langorously through a pseudo-fishtank. The tank powers down automatically after two hours, making it a handy nightlight to help the kids go to sleep. And the movement is as hypnotic as watching the real thing. It is incredibly peaceful to watch. These jellyfish are illuminated both in regular mode, and in deep sea mode, in which they turn a very deep blue and begin to swim more slowly. LED Jellyfish are $156.00, and you never, never have to clean the tank.
