Starry Night Orrery Mechanical Music Box by Robotime.
What is an Orrery? It is a mechanical model of the Solar System to illustrate the relative positions and motions of planets and moons. Invented in the 18th century, the orrery model is both an educational model and a stylish decor.
ROKR Starry Night music box gets the inspiration from that but simplifies it into a musical kit. You will see how planets orbit when music plays.
