The 150-year old mechanical music creator, Reuge, has unveiled its brilliant Butterfly project, which features two singing birds with real bird feathers. Each bird sings a different song and has a customized 72 notes movement. While inaction, there will be a little white gold butterfly moving in sync with the melodies. This creation was custom ordered by a father for his daughter, who is very fond of butterflies. How touching! The music box costs $48,270.
