MEANING
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.
