Reynolds' blog offers a plethora of insightful advice to help you make your presentations more engaging, effective, and awesomer. For example, look at how he encourages a fresh look at a tired slide in this entry: http://www.presentationzen.com/presentationzen/2005/09/whats_good_powe.html
Visit his website for more tutorials here: http://www.garrreynolds.com/Presentation/
You can (and should) download a .pdf of his handout for "How to Design & Deliver Presentations Like a Pro." ALSO - note that we have copies of reynolds' books in our library at Limestone - check them out! (Literally, check them out.)
It was through a Presentation Zen blog entry that I first ran across this great video on "The Art of Storyboarding," which illustrates the power of planning your presentation, whether it be a movie, slide show, or event.
