Presentation Zen. Simple ideas on presentation design and delivery. Garr Reynolds. 2008. ISBN 9780321525659. This picks up from Turfte’s “Beautiful Evidence” book and more so. If you give presentations at all you need this book. It is so far the best book on Powerpoint (Keynote) I have read. The ideas are not just talked about, you walk through how to do it with plenty of before and after pictures. A very graphical and stunning book. If you have ever felt that your audience was just not getting your message, or you understand why Steve Jobs out presents Bill Gates, or you appreciate the Guy Kawasaki style, then this is the book for you. Buy it, read and use it and do not lend it!
