$229.95The MOVA globe ( 12cm ) is the first member of a new family of objects that come quietly to life when touched by light, without wires or batteries. The globe floats at a point of perfect balance between buoyant forces and gravitational forces, and slowly turns as it feels the force of the Earth's magnetic field and the energy carried in light. Its perpetual, quiet motion brings a tranquil point of focus to a room. Add more light and watch Venus spin faster, dim the setting and observe it slowing. It really is an amazing sight to see! The MOVA globe works similarly to a compass in that the Earth's magnetic field makes this work!
