Bearbeitungsklappe [Editing Flap] is a book of drawings. It is also a piece of experimental video art. The book consists of ninety-five drawings that resulted from editing a video recorded through the letterbox of the artist's house in Niederbrechen, Germany. Each drawing in the publication shows an edited version of twenty-four events that took place while the video was being recorded, such as people returning from trips to the shops, cars transporting their owners to work or a cat going about its daily business.
