What is creativity anyway?

So I think that I've decided to go with the idea of learning a new movie maker software of some kind. I'm not sure which one, and I'm pretty sure I might have to purchase one to have a decent one. For now I'm trying out "One True Media," an online product. I'm going to use it to create the slideshow for my students "Peek Across the Creek" party on Tuesday. But the little I've used it, I don't think it is going to push me enough. I also don't know that I'm going to like the "restriction" it imposes (what? Me? Not like a rule?!?!). But I figure this whole process is what the project is supposed to be about, so I'm going to count this as part of my path toward a better, more user friendly movie maker product.
