The first thing that I was impress about this is the theme of the video, lifesize dolls that escaping on a big box; techniques that they did are usually you will see in old Hollywood Movies especially the part they are going out on the box, reminds me the old King-Kong movie.
Another one is the tech-sound that this track has, similar to those tracks of Deutch group Kraftwerk and also their choreography, so cool.
Another hit track from the group T-Ara: Sexy Love
