A light gun is a pointing device for computers and a control device for arcade and video games.
Modern screen-based light guns work by building a sensor into the gun itself, and the on-screen target(s) emit light rather than the gun. The first device of this type, the light pen, was used on the MIT Whirlwind computer.
The light gun and its ancestor, the light pen, are now rarely used as pointing devices due largely to the popularity of the mouse and changes in monitor display technology—conventional light guns only work with CRT monitors.

Famous quotes containing the words light and/or gun:
“The One remains, the many change and pass;
Heaven’s light forever shines, Earth’s shadows fly;
Life, like a dome of many-coloured glass,
Stains the white radiance of Eternity,
Until Death tramples it to fragments.”
—Percy Bysshe Shelley (1792–1822)
“Though I had not come a-hunting, and felt some compunctions about accompanying the hunters, I wished to see a moose near at hand, and was not sorry to learn how the Indian managed to kill one. I went as reporter or chaplain to the hunters,—and the chaplain has been known to carry a gun himself.”
—Henry David Thoreau (1817–1862)
