This is a quick diversion you can find just outside of Gangnam subway station. It's like Samsung decided they wanted to make their own permanent version of CES.
They have several stations set up, like these cycling and baseball games.
You'll find this animated LED display upstairs.
Here's a closer look at the LED display from behind.
I didn't go to CES this year. I believe this is the same Ultra HD TV they brought to Vegas in January. The picture quality is incredible.
On my way out, I saw this girl recording some sort of video segment. I'm not sure if she's famous or not, so I snapped her photo just in case.
