This is an idea right now - at the hackaday superconference in 2016, one class was creating a DJ board with capacitive paint and an Adafruit Circuit Playground with a pizza box as the medium. I participated and it was fun, however I do dumb things because I think I am smarter than I really am, and it never works out.Of course, I folded my pizza box in reverse for some reason so, like most of my projects, its a little backwards - Keep that in mind when reading through this write up.
