Back in university, we were able to print unlimited printouts on wide fanfold paper, (perhaps 128 characters wide or maybe more).  I could then unfurl the printed code out across the desks or the room and get a great overview of my code, draw circles and arrows and a paragraph on each one in the wide margin, see if this code matched that code, tweak variable names by seeing their brethren, etc, and I loved it.Right now I'm using xcode for iOS programming, but the question comes up no matter what editor I've used: how can I get a good code overview that's bigger than my screen?
