PowerPoint and visual aids in contests

There is no rule against using Powerpoint or visual aids including props in contests. Many contestants make use of them during their speeches. The contestant needs to be aware however that they have to supply all of the equipment (computer, projector and screen) they need. They also need to set up and take down everything during the one minute of silence between speakers. If something doesn't work, it is their problem to fix it while the clock is running.

I would recommend against using Powerpoint, but the contestant may decide for her/himself. Personally I'd love to see Powerpoint used in a competitive speech.
