The cut-up technique (or découpé in French) is an aleatory literary technique in which a text is cut up and rearranged to create a new text. The concept can be traced to at least the Dadaists of the 1920s, but was popularized in the late 1950s and early 1960s by writer William S. Burroughs, and has since been used in a wide variety of contexts.
Cut-up is performed by taking a finished and fully linear text and cutting it in pieces with a few or single words on each piece. The resulting pieces are then rearranged into a new text.
The challenge is to create a one-page piece of writing that uses the cut-up technique. You can use your own writing, or draw from others, i.e., magazines, newspapers, novels, etc.. You can, if you wish, also incorporate visual collage techniques, using images cut from different sources.
Think of the final product not simply as a piece of writing, but as a piece of art anchored by text.
