Wouldn't it be more interesting if it showed some sort of information about the source code? For example the edits over time similar to this project: http://www.bewitched.com/historyflow.html
Maybe, you could do it like gource. It shows a tree of your project structure that you can print off? I think that sounds pretty cool, and might be a bit quicker to generate.
I didn't work when I drag n dropped an image (just says "Rendering" indefinitely) :(
