This is the artwork I just made for my DIY CD DM's Screen.
I love the movie posters they used to make for the old Spaghetti Westerns. This mashup has art from For a Fistful of Dollars, Death Rides a Horse, Once Upon a Time in the West and Shanghai Joe. I printed this for the front of the screen (connecting the 2 CD cases) and the sides will have artwork from the posters for Django on one side and Navajo Joe on the other.
I have it printed out and assembled now and I'm pretty happy with it. It needs some cardstock inserts to hold the normal printer paper in place - so if you're making your own screen keep that in mind or print it on thicker paper.
