Drawdio is a DIY music project by designer jay silver that let’s users draw the instrument of their choice on a piece of paper and play it with their finger.
While possible to use in a variety of objects, when used with a pencil, the graphite acts as a circuit on the paper, transmitting the electric signal across the drawing to produce a different sound based on the specific form.

If you can get past the sort of hilarious / awkward editing in the video, it’s a very cool and simple design. It makes me curious about the potential for creating some kind of traceable sound-map, what sounds would Detroit’s streets make versus Windsor’s streets? What would happen if you added new roads or buildings — what sound could that make?
