I remember the first time I've seen this back in 2009 .. How hard is to make something like this ?
All they did was create one set of hair curves, and then simply animated the attributes for the hair simulation and colors. You could do this with XGen in Maya in a snap.
Doing it is moderately easy, it's just hardware intensive.
All that I really liked in this ident is [spoiler:lit]music.[spoiler:lit]
