Welcome to the weird and wonderful world of the iMu - a tiny super-energy crystal device that deploys highly effective vibration-based technologies to effectively convert any flat, hard surface into a quality audio speaker. Now read that again out loud - and think of the implications.

Now, as everything from solid wood floors to the tops of domestic appliances to car bonnets and cupboards becomes a speaker, hearing will indeed be believing. Simply place the iMu on top of any hard surface, and off you go. It's instant. It's incredible. And it actually works. So now you can take your sounds with you - and make the humblest piece of inanimate furniture a throbbing sound system.

The magic is all down to a unique composite known as Terfenol-D, developed by those jolly clever chaps at the US Navy. Place the Terfenol in an aluminium case, wrap a coil round it and pass a current through... the resultant expansion of the Terfenol creates a force capable of transmitting electrical signals (your music) into mechanical energy (vibrations). It's these good vibrations that are picked up and amplified by the hard surface on which the iMu is sitting.

Suddenly, portable music's been turned on its head. And with an iMu in your pocket, you'll be able to turn quite a few heads, too. Oh yes.
