Korean designer Rhea Jeong says she's been astounded by the amount of interest in her conceptual Void LP record player. One look at the design and you can see why it's made so much noise without even uttering a sound. Close your eyes and imagine a little red globe spinning around on top of a vinyl record emitting sound from speakers inside it. The record itself is suspended in mid-air above a simple black base unit - no strings attached, no wires holding it up and definitely no safety net. The imagery is quite simply jaw-dropping. But can such a thing really work?
