Special Effects~!! | Script Frenzy: "What you're doing now is writing a first draft. Just write it, and don't worry about how it will be created. This is not the point when you should be self-limiting.
If it helps you get past it, make a list of effects you'll need to create. Just list them, don't worry about how. Know that you can go back to the list later and figure things out.
If you find later on that there's something you just can't create, fine, rewrite then. But for now write it the way you dream it."
