This ad by CNN reminds me of a chart concept that I use often to uncover things: the zipper. It can easily be replicated in PowerPoint using two approaches:
  • Select a stock image and remove the background color if necessary. An example here, or here, or this nice bag full of cash that you will return to your investors in 4 years.
  • If you are in an artistic mood you can actually recreate the zipper using basic PowerPoint rectangles, maybe using straight lines instead of curved ones.
