It's not really cheating. I can visualize a reticule without this thing. This could also be detrimental depending on your display. If you view your screen from the wrong angle, you will start to see a parallax effect. Basically it would appear to move around depending on which angle you see it from. If you really need something like this, just take a red sharpie or some marker with fluorescent ink and put it on your display. Use rubbing alcohol on a paper towel to remove afterward.
