“Lickestra” by Carla Diana and Arone Dyer (2014)
Based on the way you lick the ice cream, the cone will respond with a sound. Using four ice cream cones, the consumer can coordinate licks with others to create a musical composition. I think the effect of being able to interpret input and base the output on the input as a specific response is pretty cool. Maybe we can try to create triggers in a similar way.
