People have a love/hate relationship with PowerPoint presentations… too many words, death by bullet point, having the speaker read the slides to them… a bad presentation can be a soul-sucking experience.

However, you can add a bit of motion and action to your slides when you go from one to another, and it can help keep your audience a bit more engaged (as in… “what’s gonna happen next time s/he changes the slide?”). You do that with Transitions.
