Animated ad - cartoons should be used more in PowerPoint
This is an ad for the Detroit Institute of Arts. It has an example of how animated cartoons can support presentations.
I should look more into their use, especially for situations that are actually hard to explain in traditional slides: for example the benefits of the product of a new technology startup that is so early-stage that it does not yet have a product demo.
More on cartoons in presentations in a post about Google Chrome.
