Hi , I never knew who to show this to? its a free app I made when I had a bad back to play miniature while I had to lydown all the time. My backs no as bad now but you guys may like to give it a go. you can put any photo of board and units into it, no setup just drop your images into the folder and there in the app. its for windows.

here a photo with my table and some juniorgeneral.org figures, I have better, but its a matter of quality images to use
