In this paper, we propose a fabrication approach to transform edible cookies into information displays. The proposed approach encodes the surface of cookie dough so that the displayed information can be changed with the user’s perspective. We use a computational design approach where small holes are pocked into cookie dough at specific angles to create shapes that are only visible from a given angle. This approach allows for selective switching of information depending on the viewer’s perspective. Our contributions include a software tool that converts images to poking patterns and a computer-aided poking machine to automatically transfer the patterns onto cookie dough. Furthermore, we demonstrate the results of visualizing information on cookies.
