Narnia

Heard about this movie and was really excited to know that Linux Clusters were used for creating the creatures in Narnia....................
Rhythm and Hues studios made a presentation in Bangalore on their experience with using Linux clusters on a large scale for the making of Narnia. They mentioned about a system called MASSIVE to animate all the creatures.
There is also a opensource API which will do the same thing.
