DIY Deluxe Magnetic Game Board & Box - The box has the whiteboard, with magnetic counters etc., mounted in the lid. Any D Day Dice (or other suitable) game "board" can be inserted.
My objective was to be able to just (digitally) paste each map / scoresheet onto the board unchanged. That's why I've gone for the landscape view. Now it's done though, I think it would be easier to use if the box was used like a book with the lid on the left and the dice tray on the right. That means making the map / score board portrait - more work!
I notice you've thumbed this image onto the first page of the BGG Creative Images Gallery! At least that brings this great game to a wider audience maybe?
