I enjoy designing PowerPoint presentations. Despite their bad reputation, I believe that the problem is not with the software itself, but rather with how is often used. To create an effective presentation is important to develop a coherent structure and memorable visuals to support the story. Over the years, I’ve created many presentations. The examples I’m sharing here have been adapted so they can be understood without me talking.
