I hope this isn't going to come across as Luddite as it might sound. But let me draw your attention to the anti-Power-Point party in Switzerland (which claims that it will save £350bn globally if we ditch PPT.. not quite sure how, but surely a good thing for the world).
I confess that I rather like some aspects of PPT. I constructed what I thought of as great slide shows in Washington DC for my NGA lectures -- entirely with PPT(though it took as long to make the PPT as it did to write the lectures) .. Credit where it's due: Therese and Mattie were very strict on the quality control of the slides (no crap images please)... and I refer you to them for further info. But that was just slides and captions, no bullet points. Indeed T and M were pretty suspicious even about the presence of captions.
But my question is: what next? I dont mean, how many pictures can you get to zoom across the screen apparently unaided, and explode in one corner to a welter of on line cheers... I am far behind that.
