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:
“A noble company gathered to develop a society that would create harmony, love, and usefulness. Now I sit on the grave of great hopes.... I look back to see a light that went out from it—small, but bright and pure and true.”
—Rebecca Buffum Spring (1811–1911)
“Every gun that is made, every warship launched, every rocket fired, signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and are not clothed. The world in arms is not spending money alone. It is spending the sweat of its labourers, the genius of its scientists, the hopes of its children.”
—Dwight D. Eisenhower (1890–1969)
