A new project from McGill University’s Input Devices and Music Interaction Lab allows users to create sounds simply by moving and touching their own bodies. These “prosthetic digital instruments” act as extensions of the human body, and were created by  a 3D printer.

“The goal of the project was to develop instruments that are visually striking, utilize advanced sensing technologies, and are rugged enough for extensive use in performance,” the University writes. One of the most interesting things about these prosthetic instruments is that it’s almost impossible for them to create the same song twice.
