Quick'n'Dirty PowerPoint

Have you ever had a mildly complicated point that you wanted to get across to just a few people? Have you ever felt trapped and confined when someone turned on a projector? I recently confronted these puzzles and explored a low-tech approach: index cards. The logic I was presenting had 9 or so steps, so I wrote each in very simple phrasing on a folded index card. It took about a minute and a half to talk through them, standing each on the table as though dealing from a deck. At that point they were a lot more useful than a slide show because they were all on the table together, instead of one at a time. As the conversation continued we could refer to them, move them around and otherwise work from a complete picture.

I'm thinking a next step might be to find do-it-yourself business cards that are made with a fold, and try using more refined text and images.
