Shake It! is a gigantic motion-based musical video game using participants’ smartphones as the controllers. Each participant is responsible for playing the right sound at the right tempo, scoring points for their team in real time, but also producing music all together as a group. On the event screen, participants follow our special moving score interface where a system of colours in motion tells them when and what to play. Instant feedback is given to each individual in the form of sound, and to each team as scores and bonuses.
