Outside of Google.co.nz too now
There is currently a storing about a secret animation in the doodle which I don't believe because these things are normally discovered by more people.
Next to that the story doesn't have any screenshots or other prove that there was an animation and besides that aprils fools is coming soon :-).
But, I need to ask, anyone noticed something?
Ok got an answer from Google saying: "No secret animation in the Houdini doodle"
