The Technology Powering Taylor Swift, Netflix and the Sphere

When the rock band Phish began their 2004 track A Song I Heard the Ocean Sing at the Sphere in April, more than 18,000 fans stared, mouths agape, as the quartet from Vermont seemingly jammed in the middle of a coral reef.

Fish — not to be confused with Phish — swam from one side of the stage to the other amid giant, pulsating jellyfish as the whole dome transformed into a trippy underwater experience. Human bodies bobbed up and down in the water amid radiant flashes of red and green. Tall plants shot up from the sea floor. The scene was just one of dozens of visuals displayed inside and on the exterior of the glowing $2.3 billion dome in Las Vegas — the most talked-about concert venue in the world.
