If you are into on-screen viewing or imaging astronomical objects a good set of crosshairs is an invaluable tool to have at your disposal. For example, you can use crosshairs to check if your camera is exactly equatorially aligned.
Many programs incorporate crosshairs which can be moved around your screen. But typically they are primarily designed to mark a particular location on the screen and so may not be able to be resized, rotated, etc.
This little program provides greater flexibility by floating a set of double crosshairs over your other on-screen displays. You can adjust the position, length, separation, thickness, and colour of the hairs. You can optionally display a center circle and also rotate the hairs into any screen orientation. A new feature added Februaury 2014 is the ability to save the crosshairs position and settings from one session to another.

You use the small Control Panel to adjust the crosshairs' position and settings.
An example of the crosshairs in use over a camera's on-screen live feed. By slewing your mount from side to side in right ascension and observing the movement of a star between the crosshairs you can tell if your camera is exactly equatorially aligned.
