Araujo uses a pencil, ruler and protractor to create these lined man made drawings. The process used is geometry which is all about shapes and their properties. I am not posting this because of the image but more for the process. I find it an interesting way to create images of objects, staying away from the modern programs we use like Photoshop and creating something with an old method to document and reference space. I enjoy that the process is documented through out the making of the drawing and by the end you have this scaffolding around the image, the lined walls which were the structures which created the drawing.
