A washing machine is a mass-produced machine which produces clean laundry (the output) from your dirty laundry (the input). But did you know that if you hack the machine by changing the input, it can also produce the output wallpaper ! By upholstering the drum with paper and filling it with uncapped marker pens, the washing machine’s usual program produces patterns. Just like an industrial process, it is parameterable, that is, you may choose between the different programs and features of the machine and utilize the features of paper and maker pens to create different outputs. Circumference and depth of the drum define the format of each unit of wallpaper. This first part of my graduation project is a hands-on reflexion on the usage of a hands-off machine.
