(glitches)

A glitch is a short-lived fault in a system, such as a transient fault that corrects itself, making it difficult to troubleshoot. The term is particularly common in the computing and electronics industries, in circuit bending, as well as among players of video games.

The annoying things that a computer does like crash, lock up, etc.
Especially used to describe idosyncracies caused by program bugs and not viruses.
My computer's got a glitch. It froze up again.

/glich/ [German "glitschen" to slip, via Yiddish "glitshen", to slide or skid] 1. (Electronics) When the inputs of a circuit change, and the outputs change to some random value for some very brief time before they settle down to the correct value. If another circuit inspects the output at just the wrong time, reading the random value, the results can be very wrong and very hard to debug (a glitch is one of many causes of electronic heisenbugs). 2. A sudden interruption in electric service, sanity, continuity, or program function. Sometimes recoverable. An interruption in electric service is specifically called a "power glitch" (or power hit), of grave concern because it usually crashes all the computers. See also gritch. 2. [Stanford] To scroll a display screen, especially several lines at a time. WAITS terminals used to do this in order to avoid continuous scrolling, which is distracting to the eye. 4. Obsolete. Same as magic cookie. [Jargon File]

A glitch is a sudden increase (around 1 part in 106) in the rotational frequency of a rotation-powered pulsar, which usually decreases steadily due to braking provided by the emission of radiation and high-energy particles. It is unknown whether they are related to the timing noise which all pulsars exhibit.

GLitcH! is a comic strip written by Ed Wiens which focuses on the adventures and mis-adventures that "Norb" and Norb's family & friends have with "GLitcH", Norb's computer.

Glitch art is the practice of using digital or analog errors for aesthetic purposes by either corrupting digital data or physically manipulating electronic devices. Glitches appear in visual art such as the film A Colour Box (1935) by Len Lye, the video sculpture TV Magnet (1965) by Nam June Paik and more contemporary work such as Panasonic TH-42PWD8UK Plasma Screen Burn (2007) by Cory Arcangel.

The following is a list of Glitch artists working in various media. Glitch artists make art based on errors and faults.
