Las Vegas lights up with dome billed as world’s largest video screen

The Las Vegas skyline has been dominated by a huge animated dome – billed as the world’s largest video screen – dwarfing surrounding high-rise hotels after going live with a 300ft eyeball looking down over the city. The show started with a welcome message, “Hello world”, followed by fireworks and stars and stripes animations, a moon in a night sky and an imposing Halloween pumpkin.
