i-Piggy is a magic audio frequency fixture. It’s quite different from traditional speakers which are based on electro-magnetic coils. The way it works is by making any hard surface such as wood, glass, floor, and metal play euphonious musical notes. Experiment with various materials around you, which have different music quality, and you’ll lose yourself in the freedom of music.
