Slides are the supporting structure for your talk, not the main event. Speak the meaty and informative portion of the presentation out loud and use slides as a backdrop to set either the emotional tone or reinforce the message that you are trying to convey.
For example, I love using this image of Obama in Berlin as a backdrop when I talk about the growth of social data over the last several years. In this image every single person has a device and is generating their own data about their shared social experience. The content of the image supports what is otherwise a fairly abstract statement, and you can feel the excitement of the crowd, boosting the excitement that I want to share about the possibilities of social data.
This is a particular style of slide design will fail for situations where “the Powerpoint” will be shared independently of the talk, and it’s not appropriate for all content, but it is a ton of fun when you can get away with it and uses people’s expectations about what they are going to see (a speaker and some slides) to create a more compelling experience.
