La Luna, which is Pixar's original short shown before Brave, I can't praise enough.
It is so charming. It has no actual talking in it, just some European-sounding gobbledegook, but the story is very clear and is just spectacular. Weaving stories like that, that is why I want to be an animator.
If you can get hold of it, watch it.
I shall be taking my copy into a tutorial to show the others!
