Harold,
I made a shift in my conference presentations this year. I used to teach people how to use visuals in their training. They 'did' it, but I also taught them how to do it. Did the how stick? Not so much.

This year, I shifted to using photos to explore a topic of common interest. So, for example, at the Brandon Hall conference, we explored: What is Innovation in Learning? Everyone has to participate.

After that conference, I got a call from an attendee saying he thought he was coming to a program about how to make his Powerpoint better, but he was sitting in the front and couldn't escape.....and thanking me because it was his favorite session at the conference (while placing an order for the VisualsSpeak tools).

My smile sheets have not suffered at all, and I get more emails and comments about favorite and best sessions than ever.

I would encourage you to go for it. And how about making posters to hang in our training rooms of that great graphic!
