Sensate and growing / decaying: custom weaving and organic material.
Continuing our research into carbon fiber as an interactive medium, these objects no longer need direct human contact. An electromagnetic field registers proximity and changes the pitch of the sound.
More importantly, new materials are introduced. Mycelium grows on the surface of the cone, and rotting liquid from a melon soaks into the carbon fiber shell. The organic material, changing over time, changes the dynamics of the interaction.
