I think Gresso will be tapping into a bit of a different demographic than Apple with their Symphonia Collection of MP3 players. The exterior case is made of African Blackwood and front surface is covered in scratch-resistant 18 carat gold. The price is between $4000-$6500, but the idea is that the audio device is interchangeable as a piece of jewelry to be worn around your neck.
It reminds a bit of the wooden labyrinth maze I used to play with when I was younger.
