EVERYTHING YOU NEED TO KNOW about the MSG Sphere. The stunning imagery produced by the sphere is done with 1.2 million hockey puck-sized LEDs that wrap around a 336 ft tall and 516 ft wide structure. The inside of the sphere seats 18,000 people with a 16K LED screen that wraps around the entire building. The sphere is equipped with roughly 160,000 speakers to provide the same audio for every seat in the building. [via thefranswah_]
