Joseph mentioned that Dick Hardt has posted his excellent Identity 2.0 presentation he gave as OSCON.
It is very easy to get the repetition/refrain that Dick uses for effect using Keynote. You simply put all the slides in an outline under the first slide of the string. Then option-drag the slide to the points in the talk you need it.
If he had more time, he could have used to new auto-build feature of Keynote to transition the slides automatically. But then again, it was somewhat amusing to see him tap away.
Lots of great ideas worthy of theft. 🙂
I promise to post my talk soon. I need bandwidth. I’m not rich like Dick.
