Emotional Connection over Visual Alacrity

Over at Sticky Slides is a great blog post about the need to connect with people emotionally. The point is that we use images for the purpose of evoking emotions in our audience. His example is the Hemingway six-word story: For sale: baby shoes; never used.

The emotional reaction from those six words is, perhaps, too complex to be conveyed by a simple image.

How can you create an emotional reaction to drive home your point?
