popcad24

PopCAD (version 1) is a paper-based 3D-input device for beginner-level 3D modeling. It connects to a piece of software to display different shapes in real-time based on the actions of the user turning on or off different lights. The lights are arranged in a 3x3x3 grid, and controlled by capacitive touch sensors made from copper tape. PopCAD is designed to be a foldable pop-up book, cheap to make, easily portable, and intuitive for novice modelers, especially children.
