"Rock It," a device from OrigAudio, brings your music to just about anything dense enough to carry a vibration. Though not a traditional speaker in itself, when paired with another hollow object (like an empty box of Cheerios), the device sends vibrations through the object, producing sound. The Rock It doesn't produce Bose-quality sound by any means, but I liked that it's capabilities only seem limited by the objects at hand. A cardboard box will produce one level of sound and a plastic ice-bucket another. Check it out!
