Enter the futuristic Sphere interior with the 로비 (Atrium) button.

Choose cyan, violet or gold atrium lighting.

Open Media Art +990 for 990 new combinations of 30 scenes, 11 color treatments and 3 motion arrangements. Choose ocean surf, fireworks, a giant eye, expressions, basketballs, liquid portals, planets, jellyfish and more. The original 990 LED shows remain: 1,980 in total. Switch collections, filter themes, look up new IDs 991–1980 or pick at random, then play on the Sphere. New scenes cover the facade without its steel grid. These are reference-inspired realtime animations, not 990 filmed videos.

In Make a Video, add scenes and edit their text, timing, speed, colors and hand-drawn LED artwork. Play your film on the Sphere, save it on this device or exchange JSON project files. Supported browsers can download WebM video. Imported video files play for the current session.

Explore the 160m-wide, 120m-tall gray steel Sphere. Choose day, night or LED show lighting, then select Aurora, Waves or Fireworks.

Press Walk and move forward through the central plaza entrance into a blue and aqua atrium with tall columns, glass balconies and suspended golden rings inspired by the supplied reference. Climb the switchback stairs on either side; at each landing, switch to the adjacent flight and reverse direction. Follow the IMAX signs along the side concourses to reach all four tiers of the preserved 4,472-seat, 45-row auditorium. Walk the same route back to the plaza.

IMAX offers a quick auditorium view. Viewing Seat selects a seat; Seat View alternates overview and side views. Jellyfish/Stars changes the immersive screen. Full View restores the plaza overview. Phone: left pad to move, drag to look. Desktop: WASD/arrows, Shift to run, Space to jump, V for camera mode. The menu retains the original city, cinema, avatar and personal-media tools. Local media lasts only for the current session.
