The intent of this project is to create an immersive experience that resonates with the wavelength of sound reverberation into a light ?instrument?. This inspiration is drawn from the ?Bianzhong?, a percussion instrument of ancient China. The tactic used to achieve this is to integrate caustic effects to mimic the patterns of sound waves. The audience is invited to become the performer of this light ?instrument,? which resonates with the wavelength of the sound reverberation. The purpose of this approach is to offer a more expansive relationship between light and sound phenomena.
