Cartoons can enhance a presentation. You need to strike a fine balance though with inviting a laugh from the audience, and trying to get your point across. People do not have time to read through a cartoon plot. The idea behind a slide should be instantly recognizable. Using classical cartoons can help. People have seen them before. Here is one that can be used to describe the low latency of a technology product. Lucky Luke, the man who can shoot faster than his own shadow. That’s pretty low latency.
The extension of the cartoon with PowerPoint shapes is not perfect. I used the “oak” standard texture, and the “Playbill” font to give that nice Wild West feel.
