tl;dr Version: Has anyone made a landscape-orientated custom GM screen?
For Christmas, I received "The World's Greatest Screen", a heavy-duty customizable GM screen. It has clear pockets on both sides of every panel, so that a GM can put in whatever they want — tables, reference stuff, artwork, a sheet of metal so that magnets can stick to it, a grid for drawing battle-maps with a wet-erase marker, et cetera. I specifically requested a landscape version, because I've always felt that your standard portrait-style GM screen puts up too much of a barrier between the GM and the players.
As a result, I now have a four-panel GM screen that isn't too tall, and can be customized to show whatever I want, both to myself and to the players. (I dislike GM screens that only show artwork on the PCs' side, especially for games that could stand to put a useful table or two up there.)
Before I can use this screen, though, I need something to show on it. I can probably put together something myself, given a bit of my all-too-scarce free time, but I'd rather not if someone else has gone through the trouble. I might use their work as a starting-point to make my own later, but in the meantime why reinvent the wheel?
