MOVA Globes are perpetually moving decorative spheres meant to capture the imagination. The MOVA Globe rotates peacefully using only the energy of room light and the forces of Earth's magnetic field. No batteries or power cords are required. Each sphere spins freely without moving off its base. The globes come in many different designs: traditional world maps, starry constellations, MOVA planets and more. With their stunning design and unique technology, MOVA Globes fit in perfectly with any home or office decor. The MOVA Globe comes in 4 sizes, including diameters of 4.5", 6", 8.5", and 10".
