Elliot's Three Basic Rules for Using Visuals in Speeches
Avoid using visuals unless absolutely necessary, then use them sparingly. (Use visuals
when you need to show something visual.)
You are the main visual, even though your body is not perfect. (Learn how not to hide
your body from the audience; stand proud and hold your ground.)
Use visuals to accent yourself, not the other way around; don't get tied up in your
visuals. (Learn to recognize how visuals can function as a crutch.)
