Peter Norvig describes how and why he turned Lincoln’s Gettysburg address into a Powerpoint presentation in The Making of the Gettysburg Powerpoint Presentation:
How many of of us have been frustrated at seeing too many presentations where PowerPoint or other visual aids obscure rather than enhance the point? After one too many bad presentations, I decided to see if I could do something about it.Back in my hotel room I imagined what Abe Lincoln might have done if he had used PowerPoint rather than the power of oratory at Gettysburg.
