Welcome to Seoul Sphere: Immersive Worlds. Admire the exterior LED facade, then press Walk to pass through the central entrance into the multi-level Sphere atrium and IMAX auditorium. The larger atrium has seven floors. Doors and walkways on floors 2 through 7 lead into the Sphere seating bowl, with fan-shaped sections and 18,000 individually spaced seats inspired by the supplied seat map.

Open Media Art to choose from the original 990 LED shows plus 1,320 new combinations across 40 Sphere scenes. Explore Glacier Canyon, Neon Whale, Meteor Storm, Coral Forest, Aurora Falls, Crystal Cave, Moonlit Garden, Ring of Fire, Cloud Whale and Prism Temple. That makes 2,310 realtime LED animations for the Sphere facade, with number search, theme filters, random selection and a video maker. Scenes are animated graphics inspired by the references.

The atrium features luminous balconies, glass rails, blue column lights, suspended rings, reflective flooring and multiple entrances. Choose IMAX to explore a seven-floor atrium leading into an 18,000-seat fan-shaped auditorium with individual seats beneath an immersive screen. Instanced rendering represents the full seat capacity.
