Giant Wave

#. Giant Wave

 

In May, there was a giant ocean wave.

It was in downtown Seoul.

But it was not real.

It was a digital wave.

A Korean company made a big digital screen.

Then, they put the screen on a building.

It covered two walls.

The screen showed a moving wave.

It looked powerful.

It even made a sound.

"The wave felt very real," one man said.
