In our experience at the West Michigan Regional and power point, it's just been our computer, us and the judges.
What we do is we provide a folder that has our submission, our presentation, with any additional notes on each slide, and any additional materials to assist the presentation. We try not to make it too over bearing for the judges with text, because there are also people speaking about the slide and about what's on there, generally saying something close to the text that's already on the slide.
The trick, as always, is to keep it within the time limit. While you may be five minutes exactly when you time it, remember that when you go to present in front of people your speech generally tends to speed up, so don't be surprised if you end earlier than you had originally timed it. Last year I had timed our presentation at four minutes and some odd seconds, and it actually turned out to be three minutes and some odd seconds, once we were done presenting. Of course, it didn't help that for some reason last year the judges for CA told us we had ten minutes to present when we had only budgeted for five. Just be ready for anything.
