"From the pendulum-based drawing machine by Eske Rex to the art of Tim Knowles who attaches writing implements to trees, I love when the seemingly random lines of chaos (or maybe just physics) are rendered visible using ink or pencil. This latest project titled STYN by Netherlands-based graduate student Sam van Doorn is no exception. Using modified parts from an old pinball machine van Doorn created a one-of-a-kind drawing device that utilizes standard flippers to control a ink-covered sphere that moves across a temporary poster placed on the game surface. He suggests that skill then becomes a factor, as the better you are at pinball the more complex the drawing becomes. See much more on his website, here. My drawing would have a single line that goes between the flippers and then have TILT written all over it. (via lustik)"
