The video below is how Hollywood makes its magic. We know that Hollywood isn't real, but who knew it was this unreal? Computer effects today are so realistic that it is hard to tell what is actual and what isn't. Even simple scenes now are computer generated.
Coke use to have its slogan, "It's the real thing!" Thank God we can't computer generate the Holy Mass. It stands on its own as the "REAL THING!" Except the Holy Mass is not a "Thing" it is an action, the action of Christ making us and the world a part of Him.
Enjoy the video, nothing religious about it, just fun to watch:
