We kind of love finding YouTube videos without descriptions. It’s endlessly fun to try to piece together what the heck is happening. In the video above, it appears as if someone is playing the old Arkanoid video game on the massive LED screen in Seoul Square in South Korea’s capital. In fact, it looks like it might just be the world’s largest LED screen. Beyond that, your guess is as good as ours. What’s the high score? How many lives do you get? How close can you sit to the screen before your mom tells you that you’re going to go blind?
