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 online explaining how to glitch
artworks. 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. 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. As a technical
word, a glitch is the unexpected result of a malfunction,
especially occurring in software, video games, images, videos,
audio, and other digital artifacts. Early examples of glitches
used in media art.
The term glitch came to be associated with music in the
mid-90s to describe a genre of experimental/noise/electronic
and other visual artists began to embrace the glitch as an
aesthetic of the digital age, glitch art came to refer to a
whole assembly of visual arts.
