Using Max to capture the pitch of the voice and a pneumatic piston to move a gas torch. Sing the right note to make the flame hit the marshmallow.
This little fun project was done for an exhibition at Godsbanen in Aarhus of the Underværker campaign by Realdania.
During the development, the first idea was just to "get fire if you hit the right pitch". But I realized, that for the interactivity to be better, you needed to have some sort of indication if you were above or below the right note - That made med change the setup to having the piston position pitch controlled.
