This interactive allows users to have several types of experience:

Memory game: The interactive turns on a series of lights, challenging users to play the spheres in the correct order. As the game progresses, it adds one more sphere each time. If users get it wrong, the interactive restarts the game.

• Free play: Users play the spheres as they would on a piano, according to their desired rhythm and taste.

• Sequence following: The lighting of the spheres guides the order in which they should be activated, so users can play a particular piece.
