Before the production of this project, we made a study phase in which we tested the interactions, experience, dynamics, hardware, and structure through a prototype. ALICE, an architecture laboratory at EPFL proposed the first car, a hack of a Smart car. This compact car was chosen because its internal proportions are already perfect for the visual and acoustic field, and because the notion of a car fits with the idea of a nomadic installation.The prototype was presented at the Montreux Jazz Festival in 2016 to a selection of musicians and journalists who evaluated the experience and gave important feedback for the production of the final model. The prototype was also used for user tests on the scenarios.
