Designer Ken Condal has built a mesmerizing subject called orrery (mechanical model of the solar system) with help by a mechanical engineering called David Clark. multiple handcrafted gears, wooden and acrylic spheres. The structure takes motion through a detail constructed system of gears activated through a winding lever at the bottom. These multilayered orrery includes the four inner planets Mercury, Venus, Earth, Mars, Jupiter and Saturn. He studied their design and assembly for three months then proceeded to work an additional seven months to finally create this sculptural orrery.
