I found this video to be fascinating - it applies video effects to the audio of the Gettysburg Address given by Abraham Lincoln. What strikes me is how the words take on a different meaning when the visuals are applied. Words that seemed to be inclusive of both the Confederate and Union soldiers who had died became a rebuke to the slave-holding practices of the South when the visuals were applied. I also felt that the end of the speech is made cynical by the subtle visual effect employed (can you spot what I did?).
Using images is a powerful way to augment the spoken word. But more than just augment, it adds another layer of meaning that can drastically change your final point. How could you use images to change your message?
