I just saw this on Twitter. K. J. Takahashi is an amazingly talented 13 year old Dubstep dancer from Dallas, Texas. Even if you don’t like dubstep, this boy’s legwork and fluidity is incredible.

ETA: Quixotic Faith (who has an awesome blog) just informed me this type of dancing is called “animating.”
My son does this type of dancing too, but he’s not THIS good.
