create something small, safe, fun and something anyone could learn to use. a drawing machine seemed the perfect fit.
i decided to use 3″ square post-it notes. the main feature is that they are self stick, so i don’t need any clamps or tape. it is also cool that you can stick them to things when the drawing is done. they are cheap and easy to find. i like the kind that have the majority of the back (full stick) covered in adhesive. this means you can use a small stack of them and peel them off as they are done.
i tried to make the drawing mechanism as tiny as possible.
