A couple of months back, I posted pictures of my own custom Humanspace Empires GM screen. Sniderman at The Savage AfterWorld has posted instructions on making your own customizable GM screen with some looseleaf binders, some plastic document protectors and, of course, duct tape.
The finished product looks good. I'll probably try my hand at one as soon as I can scratch up the cash. (Yes, I'm that broke right now.)
