The power of repeating images.
I used a stock image of a bullet going through one layer of glass as the basis for a setup page explaining how a hacker can gain access to secure data through a series of steps. As people go through the presentation, on additional layer is added to the tracker page
One image, cropped and repeated a few times. All other elements of the chart are minimalist and simple. People get the message, no need for more sophisticated graphics.
