"Things You Wouldn't Know If We Didn't Blog Intermittently."
I believe this would be considered "animation."
Stan: If you want to look into related styles, there's the Wikipedia page on "popping". It includes a small bit on the "animation" Nathan mentioned. She definitely does "floating" during part of this dance. And if you want to see another good contemporary dancer, look up Madd Chadd, who does animatronics (I recommend his LXD Oscars dance). Or Josh.0 (ElasticIllusion on youtube). He looks like a mildly creepy '50s animatronic robot when he dances. It's uncanny.
Now if only she would learn how to smile...
