The Holographic Universe is a high-tech, interactive device that projects a miniature, three-dimensional representation of the cosmos. It features a sleek, metallic base with a polished finish, supporting a translucent, glowing orb that displays celestial bodies in vibrant, luminous colors. The surface of the orb is smooth with subtle, intricate engravings of constellations, and it emits a soft, pulsating light that mimics the rhythm of the universe.
