Bug sets windows shaking: a British-designed gadget the size of a computer mouse turns any smooth hard surface into a loudspeaker. It’ll plug into a personal audio device with a regular phone plug. They’re working on a bluetooth interface for cell phones. You can use two in your car to turn the car windows into speakers, if you’re not considerate enough to care about sharing your music with everyone you’re passing by. You can even attach it to the back of your skull. BBC
