I eschew powerpoint in favour of a whiteboard, which allows me to engage with the material and the audience, through me, to also engage with the material in a way that a projector doesn't allow. This has the added benefit of allowing me to talk through points, rather than the audience reading and rushing ahead, and (know that notetaking aids memory and application) also makes it clear to the audience that they need to be responsible for notes and can't just 'have me send the slide pack'. Where I need slides - usually for graphs like stock market trends, which can be hand drawn but at the expense of credibility, I stick to Guy Kawasaki's 10/20/30 Rule - 10 Slides / (per) 20 Minutes / 30 Point font. http://blog.guykawasaki.com/2005/12/the_102030_rule.html http://blog.guykawasaki.com/2005/12/the_102030_rule.html
