Inverted color crosshair?
Hello robots. Is there any to get a small dot center of your screen that inverts all color behind it? Kind of like the Minecraft crosshair, except it is always shown in the foreground on top off all programs. My little bro plays like this on his t.v. but with small piece of tape in the exact center. It would be really useful while playing FPS games. I know I'm making things complicated, but I'd rather not have adhesive residue on my monitor.
