display hack

<graphics> A program with the same approximate purpose as a kaleidoscope: to make pretty pictures. Famous display hacks include munching squares, smoking clover, the BSD Unix "rain(6)" program, "worms(6)" on miscellaneous Unixes, and the X "kaleid(1)" program. Display hacks can also be implemented without programming by creating text files containing numerous escape sequences for interpretation by a video terminal; one notable example displayed, on any VT100, a Christmas tree with twinkling lights and a toy train circling its base. The hack value of a display hack is proportional to the aesthetic value of the images times the cleverness of the algorithm divided by the size of the code. Synonym psychedelicware.

Screensaver

A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence the name).

Screensaver

A screensaver (or screen saver) is a computer program that blanks the display screen or fills it with moving images or patterns when the computer has been idle for a designated time. The original purpose of screensavers was to prevent phosphor burn-in on CRT or plasma computer monitors (hence the name). Though most modern monitors are not susceptible to this issue (with the notable exception of OLED technology, which has individual pixels vulnerable to burnout), screensaver programs are still used for other purposes. Screensavers are often set up to offer a basic layer of security by requiring a password to re-access the device. Some screensaver programs also use otherwise-idle computer resources to do useful work, such as processing for volunteer computing projects.

As well as computers, modern television operating systems, media players, and other digital entertainment systems may include optional screensavers.
