It's time to set a new mood in the office. One that puts you right up there with Jacques Cousteau, or maybe even Captain Nemo. One that enables you to summon the monsters of the deep, almost at will. And one that casts and eerie, almost ethereal glow across your entire workspace.

Unpack your new Jellyfish tank, plug straight in to the mains, and that's exactly what awaits. This is no ordinary fishtank. No sir. For, powered by the luminescence of LED technology, it unleashes no fewer than three cyber-enhanced jellyfish, each a full three inches long and able to swim, bob and dangle dangerously all day long.

Circling menacingly with tentacles poised for action, they can have a strangely restful impact on the viewer, which, when combined with LED lighting array, gives the whole affair a unique look and feel. You can even adjust the colour theme and enable a discreet but regular change in hue - or pick the one that suits your mood and have the jellyfish perform on your command.

The LED Jellyfish Mood Lamp. It's weirdly hypnotic. Yet thoroughly distressing and strangely compelling. All in, it's nautical - but nice.
