Being a retired dancer, I love and appreciate almost anything having to do with any form of dance. Everyone has their own opinion on these kinds of things... sooooo ...I can only come up with one comment on this video...

LOL. I think the video is more about the timelapse photography technique than the dance itself. The video is essentially a series of still photographs, taken a half second apart (or some time interval) and then played one after another, much like you see with timelapse videos of flowers blooming or plants growing. The person dancing had to move very slowly.
Here's another cool video showing the technique:
