PowerPoint is so 2001. If you want to liven things up at your event, encourage your speakers to use an online presentation system like prezi.com, which lets them zoom in and out and skip around, or sliderocket.com/product, which lets presenters create seamless multimedia presentations. If they must use PowerPoint, introduce them to the HaikuDeck app. It gives presenters bold, image-driven templates that force them to think visually rather than in bullet points. If you aspire to a TED conference-type format, give your speakers a copy of “Presentation Zen” by Garr Reynolds. It’s been a must-read for TED presenters for years.
