Best web resources: Presentation Zen

Presentation Zen is a marvelous website created by Garr Reynolds. It concerns the art and craft of giving great presentations, and I always find it excellent; written with care and creativity. Garr puts a huge number of resources there, and if you like the site, you might also enjoy his personal blog. I admire Garr's creativity, constancy, sense of humor and Zen aesthetic. Also, if you're interested in Steve Jobs, there are some wonderful posts there with some of his presentations. I hope you enjoy!
