The most important element of an essay is its readability. Essay (Invisible) removes the original functionality of an essay, by changing the colour of the typed words to match that of the background on Microsoft Word, making the writing invisible. The only evidences for existence of the writing are the red lines highlighting grammar mistakes and hyperlinks. The red lines in this work are not mistakes but words and names in other languages. Therefore the software’s interpretation of mistakes, or the algorithm’s recognition of mistakes became the visible composition of the artwork. Essay (Invisible)also suggests humour as the status of the artwork could range from ‘high art’ to useless, depending on the viewer’s interpretation.
