One user: play music to control a tongue!
Two users: The Sound of Kiss facilitates an amorous ambience in which couples digitize their love while kissing. One wears a headset and the other's tongue is affixed to a magnet. When they kiss, the magnet and the electro-magnetic sensor interact to create spontaneous music. The musical composition depends on how far one's tongue is away from the other's lips/tongue and their style of action.
