The Ballagumi is a silicone form embedded with fibre-optic sensors. It responds to deformations such as bending, twisting, prodding, and slapping holistically, as the flexible substrate ensures that a deformation in one local propagates to the rest of the instrument. Conceived as a controller for physical modelling synthesis, with its many intertwined sensors mapping on to the myriad parameters of a dynamical system.
