On another note, I think the rules should have some clarification, like the effects you can and cannot use.
Like fog machines, which I think might be a problem. For several reasons, like dry ice, and being able to contain the fog, also lights I really liked the Christmas lights, and such, but my friends with FFVII church theme wanted to put strobe lights out, though they decided against it. I just think a general list of things might clear up stuff, and also cause me less hassle next year when my friends want to make a display, when they ask a question that I don't know the answer to.
