since we're not good at graphic design...

This website is run by a graphic design professor at Marietta College. I don't know much (anything actually) about Marietta College or this professor but he has some very helpful information which I think would help us on this project, and in general for that matter. I clicked on the typography class link on the right and found some interesting stuff. Look around for yourself, explore the different class pages.
