Trying out Animation Desk app for the iPad: potential book trailer use?

I've had the Animation Desk app on my iPad ($4.99 in iTunes store right now) for ages but only finally got around to trying it out recently. I created the animation above in about an hour, and that included figuring out how to use the app. I have zero animation experience but still had a lot of fun. Next time, I may try adding some audio. :-)
