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 comtemporary work such as Panasonic TH-42PWD8UK Plasma Screen Burn (2007) by Cory Arcangel.
In a technical sense, a glitch is the unexpected result of a malfunction, especially occurring in software, video games, images, videos, audio, and other digital artefacts. Early examples of glitches used in media art include Digital TV Dinner (1978) created by Jamie Fenton and Raul Zaritsky, with glitch audio done by Dick Ainsworth. This video was made by manipulating the Bally video game console and recording the results on videotape.
The term glitch came to be associated with music in the mid 90s to describe a genre of experimental/noise/electronica (see glitch music). Shortly after, as VJs and other visual artist began to embrace the glitch as an aesthetic of the digital age, glitch art came to refer to a whole assembly of visual arts.
In January 2002, Motherboard, a tech-art collective, held a glitch symposium in Oslo, Norway, to "bring together international artists, academics and other Glitch practitioners for a short space of time to share their work and ideas with the public and with each other."
On September 29 thru October 3, 2010, Chicago played host to the first GLI.TC/H, a five-day conference in Chicago organized by Nick Briz, Evan Meaney, Rosa Menkman and Jon Satrom that included workshops, lectures, performances, installations and screenings. In November 2011, the second GLI.TC/H event traveled from Chicago to Amsterdam and lastly to Birmingham, UK. It included workshops, screenings, lectures, performance, panel discussions and a gallery show over the course of seven days at the three cities.
What is called "glitch art" typically means visual glitches, either in a still or moving image. It is made by either "capturing" an image of a glitch as it randomly happens, or more often by artists/designers manipulating their digital files, software or hardware to produce these "errors." Artists have posted a variety of tutorials online explaining how to make glitch art. There are many approaches to making these glitches happen on demand, ranging from physical changes to the hardware to direct alternations of the digital files themselves. Artist Michael Betancourt identified five areas of manipulation that are used to create "glitchart." Betancourt notes that "glitch art" is defined by a broad range of technical approaches that can be identified with changes made to the digital file, its generative display, or the technologies used to show it (such as a video screen). He includes within this range changes made to analog technologies such as television (in video art) or the physical film strip in motion pictures:
