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:
“Our roots are in the dark; the earth is our country. Why did we look up for blessing—instead of around, and down? What hope we have lies there. Not in the sky full of orbiting spy-eyes and weaponry, but in the earth we have looked down upon. Not from above, but from below. Not in the light that blinds, but in the dark that nourishes, where human beings grow human souls.”
—Ursula K. Le Guin (b. 1929)
“We got our new rifled muskets this morning. They are mostly old muskets, many of them used, altered from flint-lock to percussion ... but the power of the gun was fully as great as represented. The ball at one-fourth mile passed through the largest rails; at one-half mile almost the same.... I think it an excellent arm.”
—Rutherford Birchard Hayes (1822–1893)
