An "orb" is a spherical object or shape, often used to describe a globe or ball-like form. In various contexts, orbs can refer to celestial bodies like planets and moons, or even decorative items like glass orbs used in gardens. The term is also commonly associated with the concept of light or energy spheres in spiritual or metaphysical discussions. In art and design, orbs can symbolize unity, wholeness, and infinity due to their round shape. They are often used in architecture and sculpture, as well as in technology, such as in the design of certain LED lights or 3D graphics.
