A map.. one of mine?

So its like 0130 hrs when I am typing this up. Why? because I've been up all night trying to learn InDesign so I can layout my game I am designing. InDesign is a pain in the butt. But while going through my notes and stuff, I found this little tidbit. Not sure what I would have used it for... So I decided to put it up here, see if anyone else can use it?
