Yippee, textures and tweens.
Or a bunch of tweens and a lone texture used to cover up how half-assed this is, atleast. This wasn't really any impressive from a technical standpoint. You used, what, 3 layers for each ball? When animating something that simple, you might as well just FBF it and get it over with. It would be way more characterful, and give you a valid opportnity to practise it. That is, if you even give a shit about your movie in the first place, which I doubt since it seemed lazily done anyway. Whatever, I guess.
