I've been consumed lately by the idea of taking two distinct documents and creating a large, visually interesting, static image that compares and contrasts them. I don't have time at the moment to explain how to interpret these but have a look at the images below. The blue text is the State of The Union Address for 2007 and the red is that for 2008.
Click on the images to see larger versions. The idea needs work still but it's starting to look promising.
