Too bad I'm not good at making sounds, I can make whole music tracks, but when it comes to sounds... not that skilled.
You could always make the lack of sound with flashy eye candy, but a presentation is a presentation.
When I was 16, I entered the VA Great Computer Challenge, about every school in VA participated, and my group won, not because we had fancy things (others had fancy video's in their presentations, sounds, music, animations, clip art), we won because we wrote the best stuff to explain the topic we were given.
No fancy stuff, a few graphics here and there. But we kicked ass just because of the content we gave.
In the end, that's what it is all about. But if you got the eye candy, flash away, just don't make it distracting.
*Looking at the medal just gave me flashbacks of how we won, sorry*
