The 1-Bit Symphony by Tristan Perich is a mini electronic symphony that is meant to "perform" when turned on. The symphony is actually an electronic composition of five movements within one tiny microchip, all housed in a traditional CD jewel case.
This little gadget creates an interesting dynamic between itself and the user. Tristan Perich's 1-Bit Symphony definitely makes an awesome music-making machine. However, I'm not entirely sure if I could listen to the same tune many times over.
