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:
“But seldom the laurel wreath is seen
Unmixed with pensive pansies dark;
There’s a light and a shadow on every man
Who at last attains his lifted mark—
Nursing through night the ethereal spark.
Elate he never can be;
He feels that spirits which glad had hailed his worth,
Sleep in oblivion.—The shark
Glides white through the phosphorus sea.”
—Herman Melville (1819–1891)
“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)
