A 250 meter x 30 meter LED screen was installed in Beijing as a centerpiece for The Place, which is a shopping mall located in the business district. The thing cost $32 million, is 80 feet above the ground, and actually 5 separate screens combined. It can play video games, live events, and visitors can even upload photos to view. However, it is primarily used as a virtual aquarium, with sharks and fish swimming by. Which, for $32 million, seems like a waste of money. I was just at the aquarium the other day, and they had tanks that seemed that big. And not only that, but if the attendant isn't paying attention and you have long enough arms -- free sushi.
A few more pictures and a video after the jump.
