This is a great interactive idea besides the beauty simplicity of its visual design. An exercise of combinatory storytelling with music. The project have launched 3 songs, each of them offer a different experience. You will see the videos explaining it just below but basically:
N1 - simple combinatory interaction
N2 - includes geolocation to unlock new instruments
N3 - you can choose and combine voices from 10 singers and 10 verses (depending on time of the day)
