Meh, I dunno about that. I would suppose most people would get the basic premise from it, and I worry the...novelty...of it might actually detract from the overall presentation (keep in mind, I'm thinking of my group of friends in level of maturity

). A visual aid would be great (and you'd probably get a few bonus points for using one), but it shouldn't domineer (pardon the pun

) and overshadow the speech.
