A Dancing God?

Over at the blog of our friends at the Florida Student Philosophy Blog, someone raised an interesting point on the interpretation of a line in Nietzsche's Thus spoke Zarathustra: I reproduce the post below - feel free to follow up and comment:

I was reading Thus spoke Zarathustra, and I am trying to understand what
Nietzsche is trying to say in the entry called, On Reading and Writing, where
Zarathustra says, “I would believe only in a god who could dance.”
Anybody have any thoughts
