Happy Feet available online, as well. The animation is invested heavily in motion capture technology, with the dance scenes acted out by human dancers. The tap-dancing for Mumble in particular was provided by Savion Glover who was also co-choreographer for the dance sequences. The dancers went through "Penguin School" to learn how to move like a penguin, and also wore head apparatus to mimic a penguin's beak. "Happy Feet" needed an enormous group of computers, and Animal Logic worked with IBM to build a server farm with sufficient processing potential. The film took four years to make.
