c_Vib, acronym for Cymatics_Vibrating Interactive Boards, are four sound sculptures where each piece materializes the sound, making it palpable and sensitive to being "heard" by other senses than just hearing. An invitation to active contemplation, in which the public is invited to see, hear and play in successive perceptual interrelations that lead to a multisensory immersion in sound. The c_Vib also unfolds in a show / concert, performed by a dancer and a musician, around the magical world of these sculptures that prove to be instruments of playing and dancing.
